What do you want to do with it?
Gaussian distribution, what do you want to do with that? I just recently generalized a least-square routine, such as to do gaussian fitting. Gaussian evaluation of course is just an elaboration of exp(-x**2). For reference, the Gaussian fitting routine is included in the most recent libastro tarball: http://justinpryzby.com/astro/code/ It is a from-scratch implementation, the Gaussian reduction matrix routine is also mine. The Gauss fitting routine has 1 remaining bug, I think. The best-fit seems to have a vertical offset from the input data; I haven't figured out why yet, it may be that the fitting routine itself works, but that the astronomy-specific inputs aren't right. I might have broken background estimation at some point. -- Clear skies, Justin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
