How to connect in your app

1. Download as zip.
2. Open and build solution.
3. In your project add reference to MatrixCalculateLibrary.dll

Or just install nuget package:

Install-Package AandA.MatrixCalculateLibrary -Version 1.0.0

How to use in code

Add using to list

using MatrixCalculateLibrary;

Code examples

Create matrix(array)

double[,] A = new double[3, 3]
{
	{ 3, 0, 2 },
	{ 2, 0, -2 },
	{ 0, 1, 1 }
};
double[,] B = new double[3, 3]
{
	{ 3, -1, 2 },
    	{ 1, 0, 3 },
    	{ 2, -1, 0 }
};

In examples we will use the A and the B matrixies.

Matrix sum

var result = BasicMatrixArithmetic.Add(a, b);

or

var result = A.Add(B);

Matrix subtract

var result = BasicMatrixArithmetic.Subtract(a, b);

or

var result = A.Subtract(B);

Matrix inverting

var result = InvertMatrixCalculator.CalculateInvertMatrix(A);

or

var result = A.Invert();

Matrix element cofactor

var result = MatrixCalculator.CalculateElementCofactor(0, 0, A);

or

var result = A.ElementCofactor(0, 0);

Matrix transpose

var result = MatrixCalculator.CalculateTransposeMatrix(A);

or

var result = A.TransposeMatrix();

Matrix determinant

var result = MatrixDeterminantCalculator.CalculateDeterminant(0, A);

or

var result = A.Determinant(0);

Matrix multiply

var result = MultiplyMatrixCalculator.Multiply(A, B);

or

var result = A.Multiply(B);

Matrix multiply on number

var result = MultiplyMatrixCalculator.MultiplyToNumber(A, B);

or

var result = A.MultiplyToNumber(5);
