I have a text file which has string say as (50%((15000-a)+b)). is there any way to calculate this expression.

Note that (50%((15000-a)+b) is not valid MATLAB syntax, and appears to be written in some other language: you would have to write a parser for whatever language that is. This is not a trivial task.

It seems that you are looking for functions such eval, which in fact is not recommended by forums and also by Matlab help. read
