hello to all

I have a problem that to resolve... I need to know where to find a library or some routine that calculate ....Linear least squares with nonnegativity constraints, and Nonlinear least squares with upper and lower bounds.

Thanks

- 09-15-2006juanpcHelp... library to calculate Linear and Nonlinear least squares?

Where have you looked so far?

The libraries that I looked are LAPACK and NEWMATH but I have sought on those libraries and I have not found. ...

I Know that the libraries of optimizacion of MATLAB have them ..

1) lsqnonlin - Nonlinear least squares with upper and lower bounds.

2) lsqnonneg - Linear least squares with nonnegativity constraints.

but I need them in C - 09-15-2006Salem
Maybe this one

I'm assuming that you actually know what you're doing on the math front to make a decent amount of sense of the things it offers... - 09-15-2006Adak
I googled Nonlinear ... in C library, and got a lot of hits. This one might have what you need:
