Is it possible to use gemv from BLAS directly on ARdsNonSymMatrix?

Hi, I wonder if it's possible to perform this operation:

w = alpha * matrix * v;

where matrix is of type ARdsNonSymMatrix, v and w are vectors, and alpha is a double?

There is matrix.MultMv, which does exactly that but without alpha multiplication. There's also a gemv function (it is used internally in matrix.MultMv) which could do that but the problem is A member is protected in the ARdsNonSymMatrix class.

Thank you!

Not sure. Maybe you can do M * ( a*v) ?

That's what I ended up using. Thank you! Closing then.
