'''''morder''''':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'''''
:represents:
::the number of rows in input matrix a
:The number of rows must be greater than or equal to zero, and less than the leading dimension of the matrix a (specified in lda)
'''''nN'''''
:represents:
::the number of columns in input matrix a
'''''alpha'''''
:is the scaling constant for matrix a
'''''aA'''''
:is the input matrix of float (for sgemv) or double (for dgemv) values
'''''lda'''''
:is the leading dimension of the array specified by a. The leading dimension must be greater than zero. The leading dimension must be greater than or equal to 1 and greater than or equal to the value specified in m.
'''''x'''''
:is the input vector of float (for sgemv) or double (for dgemv) values.
'''''incx'''''
:is the stride for vector x. It can have any value.
'''''beta'''''
:is the scaling constant for vector y
'''''y'''''
:is the output vector of float (for sgemv) or double (for dgemv) values.
'''''incy'''''
:is the stride for vector y. It must not be zero.
