Hi,

I am reading string data of this format from a text file:

(20:200,40:300)

This is the area of an image which I wish to select. How do I convert this string to number range. Thanks.

Hi Charles,

a simple way would be replace all non digits by spaces and use str2num afterwards:

x = '(20:200,40:300)';
x(~isstrprop(x, 'digit')) = ' ';
xNumber = str2num(x)

str2double(regexp(x,'\d+','match'))

use str2num

That won't work. He'd going to need to parse the string based on '(,:' first

As Sean de Wolski pointed out, it doesn't work.
