MATLAB: Extract decimal number from a file name

Question

Hello everyone,

Firwstly, Happy new year.

I have have a file name such as '2C2C', sometimes the number has a fraction for example '2.5C3C' or 2.5C3.5C'. I need to exract these number at all cases (with fraction and without).

Thanks in advance

Answer 1

Try this:

filnam = {'2C2C', '2.5C3.5C'};
nrs = cellfun(@(x)sscanf(x, '%fC%fC'), filnam, 'Unif',0)
Result = cell2mat(nrs).'

producing:

Result =
            2            2
          2.5          3.5
