How to change a bit of matrix from 0 to 1

Dear members,

I have a matrix

and I have to write a program that verify if the final bits are '0' or '1'. If final bits are '0' the program change them to '1'.

Answer 1

[David Hill]

M(6:11:end)=1;%for your Matrix M

[Afluo Raoual]

What is 6 and 11 please? and what about its general form if we have another matrix of other dimensions

[David Hill]

6=size(M,1)+1

11=size(M,1)*2+1

M(size(M,1)+1:size(M,1)*2+1:end)=1;

Thank you so much
