[Help-gsl] Exponential curve fit example

[Gordan Bobic]

Hi,

I'm having difficulty in getting the exponential curve fit example to 
even compile. Whenever I try it, I get undefined references to things 
like gsl_matriix_alloc and gsl_vector_view_array.

I looked through the header files and found these in gsl_vector_double.h 
and gsl_matrix_double.h, but including those didn't fix the problem.

What am I missing?
