I have a matrix and i want to create a column of zeros the size of the matrix.
M=rand(5)
A=zeros(size(M,2))
the error i get is
Index exceeds the number of array elements. Index must not exceed 2.

You have accidentally created a variable with the name rand or the name size or the name zeros
Also, to create a column of zeros you should be using
A = zeros(1, size(M,2));

The code you have posted here runs without error.
M=rand(5);
A=zeros(size(M,2));
My best guess here is that you have a variable in your workspace that has the same name as one of these functions: rand, zeros, or size.
I suggest you clear your workspace, rename any variables that have the same name as a MATLAB function, and try again.
