)

Multiplies a matrix and a vector.

• order : Whether matrices are row major order (C-Style) for column major order (Fortran-style). One of enum CblasRowMajor or CblasColMajor
• transA : Whether to transpose matrix A. One of enum CblasNoTrans, CBlasTrans.
• M : Rows in matrix A
• N : Columns in matrix A
• alpha : scalar factor for (sigma * op(A) * x)
• A : matrix A
• lda : The size of the first dimension of matrix A
• X : vector X
• incx : use every incX’th element of X
• beta : scalar factor y
• Y : vector Y
• incy : use every incY’th element of Y

For parameter lda, if you are passing a matrix A[m][n], the value of parameter lda should be m.
