Hi Ranjith,
Try typing "which class" into the command window. It should return Built-In and the path to the built-in class.m file.
From looking at your errors, it looks like you have another class.m file located at C:\Users\my laptop\Documents\MATLAB\class.m that is messing with other built-in functions

Don't name your scripts things like class, or ANY other already used name. Read what it told you:
Error using legend (line 120) Attempt to execute SCRIPT class as a function: C:\Users\my laptop\Documents\MATLAB\class.m
At the command line, type this:
which class -all
Is the first line a script of your own, called class.m? DON'T USE THAT NAME.
Remember this advice for the next time you name a script or function and save it. Otherwise, expect the same type of error.
