Add "." to simple operators such as +, *, /, ^ in order to calculate element by element values

Hi

I have an expression, say " 5A/B+C*D ". This equations came automatically in my script in Matlab. Thereafter, I need to evaluate this equation in different sets of (A,B,C,D). So, I need to change it to "5A./B+C.*D". How can I do that automatically in Matlab in through some lines? I do not want to do add "." by hand.

Your is really appreciated.

Why not? As you code, you'll be hitting keys on your keyboard thousands of times, so what's wrong with hitting "." a few times? And what do you mean those equations came automatically? Someone typed them in at some point in time, didn't they? Who gave you the script? Ask them why they didn't type it in correctly.

Previously you helped me how to solve multiple nonlinear complex equations using fsolve, fzero, and so on. Thanks again
