begin cumputer programming in C using lapack

[epifanio]

Hi

i'm new to C and Lapack,
i've only little experience with matlab/octave.

for my study i need to translate in C code an octave script.
my targhet is to compile a new function in a open source software
(grass) http://grass.itc.it/

i've notice that C do not have native higher-math functions ... so i'm looking for lapack libraries.
(but i do not know the sintax to use it)

i'm on osx
actually i'm building grass from source with blas - lapack support (using the osx veclib framework as dependancies)

can you point me to some documentation / examples on how can i use lapack ?


... apologize me for this newbie question,
thanks for any suggestion!
