Hi
Thanks for the quick reply, and I'm sorry about my late reply

A method that I need to implement on C++ needs to compute the mean and 
standard deviation of the values in a matrix. I cannot find any 
functions I can call from C++ to compute these values and google gives 
me nothing.

Typing "type mean" inside octave gives me an m-file implementation of 
the mean function. Does this mean I can't call mean from C++ ?
At the moment I have just a quick 'n' dirty implementation of mean & std 
in C++. Is this really the way to go?

De er medlemmer af "Gustav Winckler logen af 96". Når de mødes, bliver 
der rigtigt lyttet til Winckler-plader, og mon ikke "Hvide måge" af og 
til bliver lagt på grammofonen.
