*
* \param A input matrix
* \param At output matrix (transpose of A)

* \tparam MatrixType1 matrix
* \tparam MatrixType2 matrix
*
* The following code snippet demonstrates how to use \p transpose.
*
* \code
* #include <cusp/transpose.h>
* #include <cusp/array2d.h>
* #include <cusp/print.h>
*
* int main(void)
* {
* // initialize a 2x3 matrix
* cusp::array2d<float, cusp::host_memory> A(2,3);
* A(0,0) = 10; A(0,1) = 20; A(0,2) = 30;
* A(1,0) = 40; A(1,1) = 50; A(1,2) = 60;
*
* // print A
* cusp::print(A);
*
* // compute the transpose
* cusp::array2d<float, cusp::host_memory> At;
* cusp::transpose(A, At);
*
* // print A^T
* cusp::print(At);
*
* return 0;
* }
* \endcode
