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.

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

I reckon the main requested feature - to replace only whole words matching the string - is well in the title but got lost in the discussion.

@Bardo: you should accept your answer, if it resolves your original question.

Here we go:
>> regexprep('v1 = v1a','\<v1\>','v(1)')
ans =
v(1) = v1a
or as a strrep for whole words
function snew = subsname(s, old, new)
snew = regexprep(s,['\<', old,'\>'], new);
