converting a specific string to two fractions

I'm trying to write a function that takes as input a string in the form of '12/345' and would return two integers:

numerator = 12

denominator = 345

Answer 1

[Wayne King]

One way:

inputfrac = '12/345';
loc = find(ismember(inputfrac,'/')==1);
num = str2num(inputfrac(1:loc-1));
den = str2num(inputfrac(loc+1:end));

[Walter Roberson]

The find is not needed in the above:

[tf, idx] = ismember(inputfrac,'/');

loc = idx(tf);

Answer 2

[Andrei Bobrov]

numden = cellmat(@str2num,regexp( '12/345' ,'/', 'split'))

[Benjamin Isetta]

I like this one. completely different than the way I made mine.
