Error while using cellfun with a function
显示 更早的评论
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?

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?

First, you did not say if the change I proposed did what you wanted.
Second,.using a loop with the original function would likely be easier and more efficient, since you already know that the function would work in that context.
