I would like the first value in the 10x1 matrix to be copied 4 times into the second 40x1 matrix and then go to the second cell in the 10x1 matrix and copy that value 4 times in the 40x1 matrix and so on until this has been done for all values in the 10x1 matrix. Please let me know if there is a way to do this. Thank you

or
A_40x1 = kron( A_10x1 , ones(4,1) );
Hard to tell from your description.
