How to implement levmar.h library in matlab

I have been trying to utilize the levmar-2.6 library of C in matlab but couldn't do it. I was trying to run lmdemo.m but it says

Error in lmdemo (line 19)

[ret, popt, info]=levmar('expfit', 'jacexpfit', p0, x, 200, options, arg);

Can anyone give me a simple example how can i implement C library levmar in matlab to find the optimized parameter value.
