Matrix m = new Matrix(3, 3); // creates a 3x3 matrix with all elements initialized to 0
double value = m[0, 1]; // gets the value of the element in the first row and second column of the matrix
Matrix m1 = new Matrix(2, 2); m1[0, 0] = 1; m1[0, 1] = 2; m1[1, 0] = 3; m1[1, 1] = 4; Matrix m2 = new Matrix(2, 2); m2[0, 0] = 5; m2[0, 1] = 6; m2[1, 0] = 7; m2[1, 1] = 8; Matrix sum = m1 + m2; // creates a new matrix that is the sum of m1 and m2
Matrix m = new Matrix(2, 2); m[0, 0] = 1; m[0, 1] = 2; m[1, 0] = 3; m[1, 1] = 4; Matrix product = m * 3; // creates a new matrix where each element is multiplied by 3In conclusion, the System Matrix package library is used for creating and manipulating matrices in C#. It can be found in the System.Numerics namespace.
