But how to subtract an 1x3 array from an 1x9 array ? Impossible.
Best wishes

Check the sizes by adding
whos aa
whos a1
before the a2=aa-a1; line.
aa and a1 must have the same size, otherwise you get the error.

Zafar, you want to subtract 3 values from 9 values. That's not defined. One way to handle this would be
len = min([numel(aa) numel(a1]);
a2 = aa(1:len) - a1(1:len);
But I have no idea whether this makes sense in your code.
Maybe something needs to be fixed in the computation of aa and a1 such that they cannot have different sizes.
