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

thank you so much, I had deleted that file and its working fine and is there way to check the functions that are not working properly

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.

thank you so much , now figured it where the problem is coming and I have deleted the my file class.m and next time onwards I wont save like that. Is there any to find trouble shooting to list and find out the errors or function not working properly,error in predefined scripts
