* @param[out] A A is overwritten with B.
* @param[in] B The matrix to be copied.
*/
static void copy (matrix_type &A, const matrix_type &B) {
/** Result matrices should always be of the right size */
A.Resize (B.Height(), B.Width());
/** This one is pretty simple, but the order is different */
elem::Copy (B, A);
}示例2: transpose
/**
* 6.
* @brief Compute the matrix transpose.
* @param[in] A The matrix to be transposed.
* @param[out] B B is overwritten with A^{T}
*/
static void transpose (const matrix_type& A,

/** Result matrices should always have sufficient space */
B.Resize(A.Width(), A.Height());
/** Compute transpose */
elem::Transpose (A, B);
}示例3: multiply
/**
* 5.
* @brief Multiply one matrix with another.
* @param[in] A The first matrix
* @param[in] B The second matrix
* @param[out] C C is overwritten with (A*B)
*/

/** We have to do a Gemm */
elem::Gemm (elem::NORMAL, elem::NORMAL, 1.0, A, B, 0.0, C);
}示例4: negation
/**
* 7.
* @brief Compute element-wise negation of a matrix.
* @param[in] A The matrix to be negated.
* @param[out] B B is overwritten with -1.0*A
*/
static void negation (const matrix_type& A,

}示例5: minus
/**
* 4.
* @brief Subtract one matrix from another.
* @param[in] A The first matrix
* @param[in] B The second matrix
* @param[out] C C is overwritten with (A-B)

}示例6: elementwiseProduct
/**
* 16.
* @brief Compute the element-wise product of two matrices.
* @param[in] A the first matrix.
* @param[in] B the second matrix.
* @param[out] C the result, which contains A.*B.
