Description

The Matrix Multiplication block multiplies two matrix inputs:

y = u * v        % equivalent MATLAB code

The size of the output is [size(u,1),size(v,2)]. The input matrices must have sizes compatible for matrix multiplication; that is, size(u,2) must equal size(v,1).

Note
If you expect to generate code for the Matrix Multiplication block using the Real-Time Workshop, you should ensure that inputs are contiguous in memory. See the Contiguous Copy block for more information.

Dialog Box

Size of U: The size of the premultiplying matrix, u, in the format [rows columns].
Number of columns in V: The number of columns in the postmultiplying matrix, v.
