+# 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
+
+```
+$real = 1.23;
+$imaginary = -4.56;
+$suffix = 'i';
+
+$complexObject = new Complex\Complex($real, $imaginary, $suffix);
+```
+or
+```
+$real = 1.23;
+$imaginary = -4.56;
+$suffix = 'i';
+
+$arguments = [$real, $imaginary, $suffix];
+
+$complexObject = new Complex\Complex($arguments);
+```
+or
+```
+$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
+
+```
+$complexString1 = '1.23-4.56i';
+$complexString2 = '2.34+5.67i';
+
+$complexObject = new Complex\Complex($complexString1);
+echo $complexObject->add($complexString2);
+```
+or pass all values to the appropriate function
+```
+$complexString1 = '1.23-4.56i';
+$complexString2 = '2.34+5.67i';
+
+echo Complex\add($complexString1, $complexString2);
+```
+If you want to perform the same operation against multiple values (e.g. to add three or more complex numbers), then you can pass multiple arguments to any of the operations.
+
+You can pass these arguments as Complex objects, or as an array or string that will parse to a complex object.
+
+## Using functions
+
+When calling any of the available functions for a complex value, you can either call the relevant method for the Complex object
+```
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo $complexObject->sinh();
+```
+or you can call the function as you would in procedural code, passing the Complex object as an argument
+```
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo Complex\sinh($complexObject);
+```
+When called procedurally using the function, you can pass in the argument as a Complex object, or as an array or string that will parse to a complex object.
+```
+$complexString = '1.23-4.56i';
+
+echo Complex\sinh($complexString);
+```
+
+In the case of the `pow()` function (the only implemented function that requires an additional argument) you need to pass both arguments when calling the function procedurally
+
+```
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo Complex\pow($complexObject, 2);
+```
+or pass the additional argument when calling the method
+```
+$complexString = '1.23-4.56i';
+
+$complexObject = new Complex\Complex($complexString);
+echo $complexObject->pow(2);
+```

+PHP Class for handling Matrices

+
+Matrix Transform
+
+---
+
+This library currently provides the following operations:
+
+ - addition
+ - direct sum
+ - subtraction
+ - multiplication
+ - division (using [A].[B]<sup>-1</sup>)
+ - division by
+ - division into
+
+together with functions for
+
+ - adjoint
+ - antidiagonal
+ - cofactors
+ - determinant
+ - diagonal
+ - identity
+ - inverse
+ - minors
+ - trace
+ - transpose
+ - solve
+
+ Given Matrices A and B, calculate X for A.X = B
+
+and classes for
+
+ - Decomposition
+ - LU Decomposition with partial row pivoting,
+
+ such that [P].[A] = [L].[U] and [A] = [P]<sup>|</sup>.[L].[U]
+ - QR Decomposition
+
+ such that [A] = [Q].[R]
+
+## TO DO
+
+ - power() function
+ - Decomposition
+ - Cholesky Decomposition
+ - EigenValue Decomposition
+ - EigenValues
+ - EigenVectors
+
+---
+
+# 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($matrix2)->toArray());
+```
+or pass all values to the appropriate function
+```php
+$matrix1 = new Matrix\Matrix([
+ [2, 7, 6],
+ [9, 5, 1],
+ [4, 3, 8],
+]);
+$matrix2 = new Matrix\Matrix([
+ [1, 2, 3],
+ [4, 5, 6],
+ [7, 8, 9],
+]);
+
+var_dump(Matrix\multiply($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 $matrix->trace();
+```
+or you can call the function as you would in procedural code, passing the Matrix object as an argument
+```php
+$grid = [
+ [16, 3, 2, 13],
+ [ 5, 10, 11, 8],
+ [ 9, 6, 7, 12],
+ [ 4, 15, 14, 1],
+];
+
+$matrix = new Matrix\Matrix($grid);
+echo Matrix\trace($matrix);
+```
+When called procedurally using the function, you can pass in the argument as a Matrix object, or as an array.
+```php
+$grid = [
+ [16, 3, 2, 13],
+ [ 5, 10, 11, 8],
+ [ 9, 6, 7, 12],
+ [ 4, 15, 14, 1],
+];
+
+echo Matrix\trace($grid);
+```
+As an alternative, it is also possible to call the method directly from the `Functions` class.
+```php
+$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($matrix);
+```
+Used this way, methods must be called statically, and the argument must be the Matrix object, and cannot be an array.
+
+## Decomposition
+
+The library also provides classes for matrix decomposition. You can access these using
+```php
+$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();
+```
