you can use the function regexp.

example:

~isempty(regexp('scramble3','\d'))

would return a 1.

if you leave out the isempty check then it'll return 9 which is the index position of the number.

Can i ask you something else,

do you know how can i create a new string just keeping the no vowels .

Str2=scrmbl;

thanks

[Joseph Cheng]

Very simple. so lets say i create a string called VOWELS;

 vowels = 'aeiou';
 Str1 = 'scramble3';

then if i go:

 vowelIndx = ismember(Str1 ,vowels);

i would get [0 0 0 1 0 0 0 1 0]

so then if i make it

 Str2 = Str1(~ismember(Str1,vowels));

we'd get Str2 without the vowels selected in vowelIndx.

thank you

i already used

expression='[aeiou]'; startIndex=regexp(str,expression); str(startIndex)=[]; str2=str

i appreciate it :)

str='scramble3'
idx=~isempty(regexp(str,'\d','match'))

%or

idx=any(ismember(str,'0':'9'))
