Line of Code works in MATLAB script but not App Developer

The following piece of code is one small section that is giving me a problem out of a much larger project.

for f=1:length(pulsepeaktimes)
    allperiods{f}=diff(pulsepeaktimes{f});
    pulseperiod(f)= mean(allperiods{f});
end

I am getting the error : "Array indices must be positive integers or logical values"

The confusing part is that obviously the array indices are positive or logical as they are 1:length(pulsepeaktimes. The other important detail is that this piece of code is not working in the MATLAB App Developer, but it works seemlessly when I run the same code in a regular script in MATLAB.

Does anyone have any suggestions or has experienced a similar issue before?

You have a variable named diff or a variable named mean
