Matrix multiply: 1-D row vector * 3-by-3 vector

[huati]

I tried to implement Matrix Multiply: 1-D row vector * 3-by-3 vector in Labview, such as [1 2 3]*[1 2 1; 3 2 4;5 7 8].

But it seems not easy to do this.

If I use array-to-matrix function to transfer 1-D row vector array to matrix, it was always transfered to 1-D column vector matrix.

I feel it is also not convenient to initialize an 1-D row array too.  

I am new for Labview, could anybody here help me out?

Thanks a lot!

Leave the vector as a plain 1D array.

Pleae attach your code so we can have a look.

Here I attached the simple 1-D row array to matrix code. Thx.

'Leave the vector as a plain 1D array.'---What does that mean? Array can do multiply?

Use AxB.vi from the "mathematics...Linear Algebra Palette".

For example the following code does "V' x matrix" and "matrix x vector". Check the online help for details.
