Hello,
I have a problem. How I can change digits in string for example:
"A[12,12]*A[12,12]+A[9,12]*A[12,9]+A[5,2]*A[1,3]"
to have
"A[11,11]*A[11,11]+A[8,11]*A[11,8]+A[4,1]*A[0,]"
using regexprep ?
Best

You need to use a dynamic replacement string
str = '"A[12,12]*A[12,12]+A[9,12]*A[12,9]+A[5,2]*A[1,3]"';
regexprep(str, '\d+', '${num2str(str2double($0)-1)}')

and if you want to get from
'A[12,12]*A[12,12]+A[9,12]*A[12,9]+A[5,2]*A[1,3]'
that
'A[1]*A[2]+A[3]*A[4]+A[5]*A[6]'
what to do then?
