Hi, I have multiple text strings consisting of two words
separated with a "tab" looking something like below:

one two

now how do you do to split this string to two separate
strings, in this case it would be split to the strings 'one'
and 'two'.

Thanks

regexp(TheString, '([^ \t][^\t]*)', 'match')

This expression is a bit more complicated than is at first
obvious because I detect that there is a space after the tab
but your output does not want the space as part of the output string.
You have not specified, though, what you want to have happen if there
are spaces within the fields.

Hi,

If there are just two words, strtok could be used.
help strtok for more.

with regards,

one of the many solutions

s=sprintf('one\ttwo three\tfour');
r=regexp(s,'\t','split')
% r = 'one' 'two three' 'four'
