Matrix-matrix product, since we view vectors as nero column widget windows matrices, the matrix-vector product nero is simply a outlook special includes case of the matrix-matrix product (i.e., a product between two matrices).

here are definitions for a matrix m and editor a vector v: In5: Out5, this leftmultiplies the vector v.
