Where do you want to show them? On a figure object, MATLAB fully supports latex or tex syntax. You can use, e.g., text(yourXvalue, yourYvalue, 'sin(\theta)') to show this on an axis at place defined by (yourXvalue, yourYvalue).

I dont want to show on figure. I want to use phi symbol in my mfile. Sin(\phi) does not work.

I don't think it works in mfile. You'd better use the English version, say, theta, directly as the variable name.
