The library currently provides the following operations:
- addition
- subtraction
- multiplication
- division
- division by
- division into
together with functions for
- theta (polar theta angle)
- rho (polar distance/radius)
- conjugate
* negative
- inverse (1 / complex)
- cos (cosine)
- acos (inverse cosine)
- cosh (hyperbolic cosine)
- acosh (inverse hyperbolic cosine)
- sin (sine)
- asin (inverse sine)
- sinh (hyperbolic sine)
- asinh (inverse hyperbolic sine)
- sec (secant)
- asec (inverse secant)
- sech (hyperbolic secant)
- asech (inverse hyperbolic secant)
- csc (cosecant)
- acsc (inverse cosecant)
- csch (hyperbolic secant)
- acsch (inverse hyperbolic secant)
- tan (tangent)
- atan (inverse tangent)
- tanh (hyperbolic tangent)
- atanh (inverse hyperbolic tangent)
- cot (cotangent)
- acot (inverse cotangent)
- coth (hyperbolic cotangent)
- acoth (inverse hyperbolic cotangent)
- sqrt (square root)
- exp (exponential)
- ln (natural log)
- log10 (base-10 log)
- log2 (base-2 log)
- pow (raised to the power of a real number)

# Installation
```shell
composer require markbaker/complex:^1.0
```
# Important BC Note
If you've previously been using procedural calls to functions and operations using this library, then from version 3.0 you should use [MarkBaker/PHPComplexFunctions](https://github.com/MarkBaker/PHPComplexFunctions) instead (available on packagist as [markbaker/complex-functions](https://packagist.org/packages/markbaker/complex-functions)).
You'll need to replace `markbaker/complex`in your `composer.json` file with the new library, but otherwise there should be no difference in the namespacing, or in the way that you have called the Complex functions in the past, so no actual code changes are required.
```shell
composer require markbaker/complex-functions:^3.0
```
You should not reference this library (`markbaker/complex`) in your `composer.json`, composer wil take care of that for you.
# Usage
To create a new complex object, you can provide either the real, imaginary and suffix parts as individual values, or as an array of values passed passed to the constructor; or a string representing the value. e.g
```php
$real = 1.23;
$imaginary = -4.56;
$suffix = 'i';
$complexObject = new Complex\Complex($real, $imaginary, $suffix);
```
or as an array
```php
$real = 1.23;
$imaginary = -4.56;
$suffix = 'i';
$arguments = [$real, $imaginary, $suffix];
$complexObject = new Complex\Complex($arguments);
```
or as a string
```php
$complexString = '1.23-4.56i';
$complexObject = new Complex\Complex($complexString);
```
Complex objects are immutable: whenever you call a method or pass a complex value to a function that returns a complex value, a new Complex object will be returned, and the original will remain unchanged.
This also allows you to chain multiple methods as you would for a fluent interface (as long as they are methods that will return a Complex result).
## Performing Mathematical Operations
To perform mathematical operations with Complex values, you can call the appropriate method against a complex value, passing other values as arguments
```php
$complexString1 = '1.23-4.56i';
$complexString2 = '2.34+5.67i';
$complexObject = new Complex\Complex($complexString1);
echo $complexObject->add($complexString2);
```
or use the static Operation methods
```php
$complexString1 = '1.23-4.56i';
$complexString2 = '2.34+5.67i';
echo Complex\Operations::add($complexString1, $complexString2);
```
If you want to perform the same operation against multiple values (e.g. to add three or more complex numbers), then you can pass multiple arguments to any of the operations.
You can pass these arguments as Complex objects, or as an array, or string that will parse to a complex object.
## Using functions
When calling any of the available functions for a complex value, you can either call the relevant method for the Complex object
```php
$complexString = '1.23-4.56i';
$complexObject = new Complex\Complex($complexString);
echo $complexObject->sinh();
```
or use the static Functions methods
```php
$complexString = '1.23-4.56i';
echo Complex\Functions::sinh($complexString);
```
As with operations, you can pass these arguments as Complex objects, or as an array or string that will parse to a complex object.
In the case of the `pow()` function (the only implemented function that requires an additional argument) you need to pass both arguments when calling the function
```php
$complexString = '1.23-4.56i';
$complexObject = new Complex\Complex($complexString);
echo Complex\Functions::pow($complexObject, 2);
```
or pass the additional argument when calling the method
```php
$complexString = '1.23-4.56i';
$complexObject = new Complex\Complex($complexString);
echo $complexObject->pow(2);
```

If you've previously been using procedural calls to functions and operations using this library, then from version 3.0 you should use [MarkBaker/PHPMatrixFunctions](https://github.com/MarkBaker/PHPMatrixFunctions) instead (available on packagist as [markbaker/matrix-functions](https://packagist.org/packages/markbaker/matrix-functions)).
You'll need to replace `markbaker/matrix`in your `composer.json` file with the new library, but otherwise there should be no difference in the namespacing, or in the way that you have called the Matrix functions in the past, so no actual code changes are required.
```shell
composer require markbaker/matrix-functions:^1.0
```
You should not reference this library (`markbaker/matrix`) in your `composer.json`, composer wil take care of that for you.
# Usage
To create a new Matrix object, provide an array as the constructor argument
```php
$grid = [
[16, 3, 2, 13],
[ 5, 10, 11, 8],
[ 9, 6, 7, 12],
[ 4, 15, 14, 1],
];
$matrix = new Matrix\Matrix($grid);
```
The `Builder` class provides helper methods for creating specific matrices, specifically an identity matrix of a specified size; or a matrix of a specified dimensions, with every cell containing a set value.
```php
$matrix = Matrix\Builder::createFilledMatrix(1, 5, 3);
```
Will create a matrix of 5 rows and 3 columns, filled with a `1` in every cell; while
```php
$matrix = Matrix\Builder::createIdentityMatrix(3);
```
will create a 3x3 identity matrix.
Matrix objects are immutable: whenever you call a method or pass a grid to a function that returns a matrix value, a new Matrix object will be returned, and the original will remain unchanged. This also allows you to chain multiple methods as you would for a fluent interface (as long as they are methods that will return a Matrix result).
## Performing Mathematical Operations
To perform mathematical operations with Matrices, you can call the appropriate method against a matrix value, passing other values as arguments
```php
$matrix1 = new Matrix\Matrix([
[2, 7, 6],
[9, 5, 1],
[4, 3, 8],
]);
$matrix2 = new Matrix\Matrix([
[1, 2, 3],
[4, 5, 6],
[7, 8, 9],
]);
var_dump($matrix1->multiply($matrix2)->toArray());
```
or pass all values to the appropriate static method
```php
$matrix1 = new Matrix\Matrix([
[2, 7, 6],
[9, 5, 1],
[4, 3, 8],
]);
$matrix2 = new Matrix\Matrix([
[1, 2, 3],
[4, 5, 6],
[7, 8, 9],
]);
var_dump(Matrix\Operations::multiply($matrix1, $matrix2)->toArray());
```
You can pass in the arguments as Matrix objects, or as arrays.
If you want to perform the same operation against multiple values (e.g. to add three or more matrices), then you can pass multiple arguments to any of the operations.
## Using functions
When calling any of the available functions for a matrix value, you can either call the relevant method for the Matrix object
```php
$grid = [
[16, 3, 2, 13],
[ 5, 10, 11, 8],
[ 9, 6, 7, 12],
[ 4, 15, 14, 1],
];
$matrix = new Matrix\Matrix($grid);
echo $matrix->trace();
```
or you can call the static method, passing the Matrix object or array as an argument
```php
$grid = [
[16, 3, 2, 13],
[ 5, 10, 11, 8],
[ 9, 6, 7, 12],
[ 4, 15, 14, 1],
];
$matrix = new Matrix\Matrix($grid);
echo Matrix\Functions::trace($matrix);
```
```php
$grid = [
[16, 3, 2, 13],
[ 5, 10, 11, 8],
[ 9, 6, 7, 12],
[ 4, 15, 14, 1],
];
echo Matrix\Functions::trace($grid);
```
## Decomposition
The library also provides classes for matrix decomposition. You can access these using
```php
$grid = [
[1, 2],
[3, 4],
];
$matrix = new Matrix\Matrix($grid);
$decomposition = new Matrix\Decomposition\QR($matrix);
$Q = $decomposition->getQ();
$R = $decomposition->getR();
```
or alternatively us the `Decomposition` factory, identifying which form of decomposition you want to use
```php
$grid = [
[1, 2],
[3, 4],
];
$matrix = new Matrix\Matrix($grid);
$decomposition = Matrix\Decomposition\Decomposition::decomposition(Matrix\Decomposition\Decomposition::QR, $matrix);
$Q = $decomposition->getQ();
$R = $decomposition->getR();
```
