Hi, I have a string of numbers of in the format '7646 89:89'. I basically want to remove the numbers following the white space e.g I want '7646 89:89' to become '7649'. Thanks

s='7646 89:89';
d=textscan(s,'%f*');
d=d{1};

TEXTSCAN is very powerful, and in consequence it is slow.

Faster than the very powerful TEXTSCAN:
s = '7646 89:89';
d = strtok(s, ' ');
Or simply:
d = strtok(s);
Or:
index = strfind(s, ' ');
d = s(1:index(1));
