MATLAB: Undefined function or variable ‘nrbevalIGES’.

igesnrbevaliges

Greetings.
I keep failing to convert (several different) *.igs files (from different sources on grabcad.org) to matlab format, always getting this error:
Undefined function or variable 'nrbevalIGES'.
I get this error when I run the iges2matlab function:
iges2matlab('function_name.igs')
and when I run this line of code from the IGES toolbox
[ParameterData,EntityType,numEntityType,unknownEntityType]=iges2matlab('example.igs')
Does anyone know the (possible) source of my problem and/or a solution to it?
Many thanks in advance,
Fardad

Look in the comments on the submission:
deng deng helpfully added:
===Undefined function or variable 'nrbevalIGES' 
===I GOT THE SOLUTION. 
===if you wanna use this toolbox, first set is to compile C file in the toolbox 
===and the author set "makeIGESmex.m" to finish the compiling 
===but if you open this file, you will find "try" structure, which  means that even though the compile fails, there won't be errors. 
===so you need to run mex('xxx.c'), and see what would happen 
===for me, MinGW-w64 C/C++ is needed, so after intalled this compiler, everything was ok 
hopefully it could help you guys
