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.

@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]
