gemmt< Rows1, Cols1, Cols2 > Class Template Reference

class for for product matrix-transpose(matrix) operations. More...

#include <tvmet/loop/Gemmt.h>

Detailed Description

template<std::size_t Rows1, std::size_t Cols1, std::size_t Cols2>
class tvmet::loop::gemmt< Rows1, Cols1, Cols2 >

class for for product matrix-transpose(matrix) operations.

using formula

\[ M_1\,M_2^{T} \]

Example:
 template<class T, std::size_t Rows1, std::size_t Cols1, std::size_t Cols2>
 inline
 void
 prod(const Matrix<T, Rows1, Cols1>& lhs, const Matrix<T, Rows2, Cols1>& rhs,
     Matrix<T, Rows1, Rows2>& dest)
 {
   for (std::size_t i = 0; i != Rows1; ++i) {
     for (std::size_t j = 0; j != Rows2; ++j) {
       dest(i, j) = tvmet::loop::gemmt<Rows1, Cols1, Cols1>().prod(lhs, rhs, i, j);
     }
   }
 }
Note:
The number of cols of rhs matrix have to be equal to cols of rhs matrix. The result is a (Rows1 x Rows2) matrix.
