Matrix to Vector

[Amer7]

Hi,
I'm facing some issues again around matrices.

When I multiply two matrices and the product of a matrix is [1,1] Matrix, I want to turn this Matrix to a Vector [1].

lets say
M22 is my matrix [1,1]
when i type
M23:=vector(M22);

It doesn't work, why I need this vector is to be able to be able to multiply matrix by a vector. - And later view the Values in Matrix editor Using EDITMAT()

Like In Matrix menu - There is an option to Edit, Delete, Vect, Send
When You press Vect it vectorises the matrix turning it [1] I need this, but what is the programing command?

Because when I use M22[1,1] in this form
Ss0:=M22[1,1];
M75:=M20*Ss0;
EDITMAT(M75,"Matrix product of M20 and Ss0");

I get Input Error
