As you see in your attempt, also the first "(-1)" gets replaced, which is exactly what the regexprep example command (in MATLAB) avoids.hmmm ... Matlab gives me the result below ...g='x^(-1)+y(-1)+z(-1)=0'; regexprep(g,'(?<=[a-z]*)\(\-[1-9]*\)','\_minus1')ans = x^_minus1+y_minus1+z_minus1=0 What does matlab give you?
