Non linear fit in octave

Hi, I  would  like to   fit some one-dimensional   data  to a  nonlinear
function, namely Y=v.*X.^(2*h), where I want to find v and h.

I found  ftp://ftp.mathworks.com/pub/contrib/v4/optim/curvefitnl.m,  but
it uses a leastsq function that, it seems, does all the job.  I guess it
is a standard function of matlab.  So I'm stuck.  Any suggestions?

Thanks to everybody
