MATLAB: String to num

string to number

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)
