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

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
