How can I withdraw a colon operator from a string

I have a colon operator within a string input (<1x30> char) that I would like to withdraw for later plotting.
The variable input is this:
WIND = NORTHEAST WINDS 8 : 13 KNOTS
I want just the characters
'8 : 13'
and make them operate as a colon operator. I was thinking of using a variation of 'find' command, but I don't know how to tell MATLAB to find colon operators within a text string.
Can you please help?

c1='WIND = NORTHEAST WINDS 8 : 13 KNOTS'
a=regexp(c1,'[0-9]')
result=c1(min(a):max(a))

Mr. Azzi's technique is more general, and I would use it for your purpose.
However, if you did want to use 'find' to locate specific characters in a text string, you can do it simply as:
a = 'WIND = NORTHEAST WINDS 8 : 13 KNOTS'
location = find(a==':');
