Transpose

The transpose of matrix M, written as Transpose is a matrix in which every element i, j equals the element j, i of the original matrix. The transpose of a matrix can be acquired by reflecting the matrix over its main diagonal, writing the rows of M as the columns of Transpose, or by writing the columns of M as the rows of Transpose. We can express the transpose for each component of a matrix with the following equation:

Transpose

The transpose operation replaces the rows of a matrix with its columns:

Getting ready

We're going to create a non-nested loop that serves as a generic Transpose function. This function will be able to transpose matrices of any dimension. We're then going to create Transpose functions specific to 2 X 2, 3 X 3, and 4 X 4 matrices. These more specific functions are going to call the generic Transpose with the appropriate arguments.

How to do it…

Follow these steps to implement a generic transpose function and transpose functions for two, three and four dimensional square...
