Hello everyone,
I am trying to round figures in a cell array however in that same array I also have string types. round changes the value of the string therfore I can't use formulas like
cellfun(@(x)round(x,N),c)
I mean I don't how to integrate `isnumeric` to this formula.
Is there a fomula that knows to round only numeric number?
Thank you in advance.

idx = cellfun(@isnumeric,C);
C(idx) = cellfun(@(x)round(x,N),C(idx),'uni',0)

@Jack Arnoldi: you are right, I forgot the 'UniformOutput',false. I have fixed my answer:
>> C = {1.234,'cat';'hat',5.6789}
C =
[1.234] 'cat'
'hat' [5.6789]
>> idx = cellfun(@isnumeric,C);
>> C(idx) = cellfun(@(x)round(x,2),C(idx),'uni',0)
C =
[1.23] 'cat'
'hat' [5.68]
