So I have written the following 4*3 matrix but I want to construct it with 'ones' and '.*' but I am unsure how to.
[12 2 1; 4 12 1; 6 2 1; 2 4 1];

Hi,
I don't know if I understood correctly, but you can concatenate two matrices:
  • M1 = ones( size(M) ); --> matrix of '1';
  • M2 = sym('.*',[4 3]); --> symbolic matrix 4x3;
BR,

This seems like a good idea, but I can't seem to run the script.
