Posted:

im trying to do a fitting between a vector and a function .
my vector is a intensity summed by 20 degree angle (160180) as a function of the beam radius, as the following pics describe : this is the picture : http://postimage.org/image/baff0lf63/ the imagesc pic after cutting by angle plus intensity graph by radius ( the angle is summed ) : http://postimage.org/image/s9l2d8j5b/
my try to to do fitting with cftool : http://postimage.org/image/6so1ugaeh/
the function i try to do fitting with : sin(b*sin(atan(x./0.05)).^2).^2+c which i took from theory .
as you can see the fitting is total joke, and ideas ?
