Parameters

transposeOperation  TransposeOperation

Specifies the operation to be performed on the matrix a.

m  Int32

The number of rows in the matrix a.

n  Int32

The number of columns in the matrix a.

kl  Int32

The lower bandwidth of the matrix a.

ku  Int32

The upper bandwidth of the matrix a.

alpha  T

The scalar used to multiply the matrix-vector product.

a  TMatrix

A span that contains the elements of the matrix.

x  TVector

A reference to a one-dimensional array containing the elements of the vector x.

beta  T

The scalar used to multiply y.

y  TVector

A reference to a one-dimensional array containing the elements of the vector y. The elements of y are overwritten with the result.

This method is similar to the BLAS routine DGBMV.
