Function rgsl::cblas::level2::sgemv

pub fn sgemv(order: Order, transA: Transpose, M: i32, N: i32, alpha: f32, A: &[f32], lda: i32, X: &[f32], incx: i32, beta: f32, Y: &mut [f32], incy: i32)

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.
