How to find the firs numeric data in varargin?

Answer 1

[Kirby Fears]

If the below code is not the answer you want, please elaborate on your question.

function MrM(varargin)
    firstnum=find(cellfun(@(s)isnumeric(s),varargin),1,'first');
    disp(firstnum);
end

[Mr M.]

what if varargin contains no numeric value?

[Kirby Fears]

Then firstnum is empty. You can use

 isempty(firstnum)

to know if numerical input was provided or not. You can use error handling like

 if isempty(firstnum),
     error('MrM() requires at least one numerical input');
 end

Hope this helps.
