I want to write a code where you can input a string of a polynomial for instance '2x+3' and matlab returns the string as '2*x+3'. The user can input any string of a polynomial and matlab adds the * where needed.
I was thinking of possibly using a for loop (length of the string) where it passes through each indices and use isletter or isnumeric and if I get a numeric followed by a letter The code addes a * in between.
Can someone help me implement this or have a better way of doing so. Thanks a lot!
