Colleagues
I would appreciate some help with regular expressions.
I have string that looks like:
" ITERATION ,THETA1 ,THETA2
,THETA3 ,THETA4 ,THETA5
,THETA6 ,THETA7 ,SIGMA(1,1)
,SIGMA(2,1) ,SIGMA(2,2)”
In the entries that contain:
(X,Y) # for example, SIGMA(1,1)
I would like to replace the comma with a period, e.g., SIGMA(1.1) but NOT the
other commas
The end-result would be:
" ITERATION ,THETA1 ,THETA2
,THETA3 ,THETA4 ,THETA5
,THETA6 ,THETA7 ,SIGMA(1.1)
,SIGMA(2.1) ,SIGMA(2.2)”
Can someone provide the regular expression code to accomplish this?
Thanks.
