Hi im trying to use regexp to get some 1,2 and 3 digit numbers from a string of symbols and numbers, for example:
so far im using regexp(string,'\d+','match') which is returning ans=['3' '2' '100'] and where:
ans(1)='3' which doesnt seem to be a number or a string.. how can i change this/these numbers to make them of some use?

s = '32100';
out = regexp(s,'\d+','match');
regexp returns the result in a cell array. Thus you cannot directly convert a cell that contains a string number into a proper double.
cellfun loops for each cell and applies the function specified after teh handle @
You have to acces the cell
