A .NET implementation of matrices and their operations.

In mathematics, a matrix (plural matrices) is a rectangular array of numbers, symbols, or expressions. The numbers, symbols or expressions in the matrix are called its entries or its elements. The horizontal and vertical lines of entries in a matrix are called rows and columns, respectively.

From Wikipedia.

Matrices are commonly written in box brackets or large parentheses:

A matrix can be created using a multidimentional array of elements.

var elements = new[,]
{
    {1, 0, 0},
    {0, 1, 0},
    {0, 0, 1}
};

matrix = new Matrix<int>(elements);

This creates an identity matrix of size 3.

A matrix can be created using a builder method, delegating the process of creating the set of elements to another object.

Func<int, int, int> delegateBuilder = (i, j) => i == j ? 1 : 0;

matrix = new Matrix<int>(3, 3, delegateBuilder);

This creates an identity matrix of size 3.

The elements can be reteieved using the indexer of the matrix object.

var i = 0, j = 0;

var firstElement = matrix[i, j];

var ith = matrix.NumberOfRows;
var jth = matrix.NumberOfColumns;

var sum = matrix1 + matrix2;

var product = matrix * scalarValue;

var matrixResult = matrixLeft * matrixRight;
