Description

Each of these functions computes the transpose of the input matrix.

For real data, the following equation is used:

z[j*m + i] = x[i*n + j]

where i = 0, 1, ..., (m - 1); j = 0, 1, ..., (n - 1).

For complex data, the following equation is used:

z[2*(j*m + i)]     = x[2*(i*n + j)]
z[2*(j*m + i) + 1] = x[2*(i*n + j) + 1]

where i = 0, 1, ..., (m - 1); j = 0, 1, ..., (n - 1).

Parameters

Each of the functions takes the following arguments:

z

Pointer to the destination matrix. The output data type must be the same as the input data type.

x

Pointer to the source matrix.

m

Number of rows in the source matrix.

n

Number of columns in the source matrix.

Return Values

Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
