help polyshape

Once you learn to create a polyshape, which is very easy. In fact, there are examples of using polyshape right in the help.

Then look at isinterior, which tests to see if a point is inside the polyshape you just created.

help isinterior

polyshape not found.

Use the Help browser search field to search the documentation, or

type "help help" for help command options, such as help for methods.

please help

Then you apparently have an old copy of MATLAB. It always helps if you tell us what release you have, otherwise you will get answers that are invalid for you.

The solution is to either upgrade your MATLAB release, as there are many things that have been introduced over the years, OR you can use an older tool that has been in MATLAB for many years: inpolygon.

Read the help for inpolygon. It will have examples of use in there.
