Transpose Matrix

This algorithm finds the transpose of a given matrix. The transpose of a given matrix is formed by interchanging the rows and columns of a matrix.

Example

									int** m1 = CreateMatrix(2, 3);
m1[0][0] = 1;
m1[0][1] = 2;
m1[0][2] = 3;
m1[1][0] = 4;
m1[1][1] = 5;
m1[1][2] = 6;

Matrix matrix = { m1, 2, 3 };
Matrix transpose = TransposeMatrix(matrix);
								

Output

									[0][0] = 1
[0][1] = 4
[1][0] = 2
[1][1] = 5
[2][0] = 3
[2][1] = 6
