What are the sizes of X, c and e?
size(X)
size(c)
size(e)
What do you mean by "doesn't work"? If you get an error message, please give the full text of the error message?

It's important to include the error message or specify what you mean by "doesn't work". Because you don't give us your variables c or X, or tell us what you are trying to do, how can we possibly guess?

If the number of rows in c and X are not the same, matlab will complain.
