I have a cell array that is empty.
I want to create an if then statement that would let me set any vector that turns out to be empty..to equal zero.
I've tried using the null statement, but I'm running into problems. Does anyone know how I could do this? It does not have to be an if then statement.

It may seem to you that you are stating your problem clearly, but I for one do not really understand at all what you are trying to do. Remember, we don't know anything at all about your problem, except what you say here.
Can you give an example of the input you have, and the output you expect from the algorithm you want. Can you show us the code you have that is not working, and describe what specifically went wrong?

Sorry!
stopcodon1 =
{[]}
if 1==isempty(stopcodon1)
stopcodon1=0;
end
My most recent attempt to make stopcodon=0. And it didn't seem to do anything.

idx = cellfun(@isempty, stopcodon1);
stopcodon1(idx) = {0};
