Implicit matrix expansion correction

I have the following line of code (running in Matlab2016b), but which shows up with a "matrix dimensions must agree" error in Matlab2015a. How would I correct it? Thank you!

a=reshape(a(a ~= b(:,2)'),[],c);

It would have been helpful if you'd provided more details such as the size of a, b and c. Most likely,

a = reshape(a(bsxfun(@ne, a, b(:, 2)'), [], c);

would solve the problem. If not, provide more details.

While you're at it rename these extremely meaningless variable names to something a lot more meaningful.

Thank you. a is 11x21, b(:,2)' is 1x21, and c is 21.
