MATLAB: Regex replace whole word

MATLABstrings

Hi,
How to change
'v1 = v1a;'
to
'v(1) = v1a;'
using regex or regexrep?
regexprep('v1 = v1a','\bv1\b','v(1)')
apparently does not work.

Best Answer

>> regexprep('v1 = v1a','^([a-z]+)(\d+)','$1($2)')
ans = v(1) = v1a
Hopefully you are not constructing arbitrary strings of code for evaluating!
