Hello,
Thanks for the tip, it worked just fine.
How can I get the correlation coefficient?
Thanks,
Cinthia Pinke

Please see the first example. You need to feed polyfit two vectors, x and y of the same size.
so define x and y separately in your case it looks like:
x = [1, 2, 3, 4, ....]
y = [ 73, 99, 90, 24...]
and finally n is the number of points you want to fit the array to. n can equal up to # of point - 1.

Dear Sir/ Madam
I am new to Octave, and I was not able to work with the polyfit function.
I have the matrix listed below and I want to find the polynomial coefficients that fit to the points x,y:
What should I do?
Thanks in advance,
Cínthia Pinke
