I am using cellfun to apply a function on train and test variables for feature extraction. The function works absolutely fine when used without cellfun but with cellfun it gives an error. The code which I'm running:

RRTrain1 = cellfun(@(x)[rrvec] == RRfeatures(x),XTrain,'UniformOutput',false);

And this is the error which is appearing,

Unrecognized function or variable 'rrvec'.
Error in @(x)[rrvec]==RRfeatures(x)

However, rrvec is already declared within RRfeatures function. Can anyone please suggest how to solve this issue?

在 MATLAB Online 中打开

Try this instead —

RRTrain1 = cellfun(@(x)RRfeatures(x),XTrain,'UniformOutput',false);

I have no idea if that will do what you want.

More importantly, if the function works fine on its own, is there a specific reason for using cellfun?

I solved the issue. It did not work that way. I had to use a counter instead of a loop. That served my purpose. Thank you for your help.
