I need an algorithm for developing a calculator application. When I googled , I got results that perform the ordinary push and pop operations . I need the complete algorithm that can be useful to code a calculator application in GUI.

What is the goal of your project?

You could just download a library that evaluates mathematical expressions (or use a language feature like 'eval') and then have your GUI build strings to feed it.

If you want to know how expressions are parsed you might want to look into lex and yacc

I don't know matlab very well, but I'm guessing you don't need to worry about the algorithm, just use their GUI library to build strings and then feed those strings into matlab's eval function.
