problem in running mex file

I am unable to run the function InPolygon available at the Matlab webpage < https://www.mathworks.com/matlabcentral/fileexchange/20754-fast-inpolygon-detection-mex >.

I am getting error "Cannot find an exact (case-sensitive) match for 'InPolygon' "

cd to the directory that contains InPolygon_Test.m

Give the MATLAB command

mex InPolygon.c

Provided that you have a compiler set up, it will create the necessary DLL. You can then test with

InPolygon_Test

There is no .m file so getting the error.

InPolygon .m

The Folder conntains

InPolygon .c 
InPolygon .dll
InPolygon_Test.m

You could see the details

Yes it work,

It was showingfollowing error to install compiler:

Error using mex

No supported compiler was found. You can install the freely available MinGW-w64 C/C++ compiler; see Install MinGW-w64 Compiler. For more

options, visit https://www.mathworks.com/support/compilers.

I installed the compiler and it works.

Thanks @James & @Walter

Sorry, I should have named the .c not the .m
