Re: [Help-gsl] Linear least squares, webpages and the next release
For everyone who said they’d like to contribute, but feel like their coding isn’t up to GSL standards: don’t worry! This isn’t the Linux kernel, you won’t get called stupid for doing your best. Patrick and the others are generally helpful and will help you to get your code included. I think it would be a shame if potential improvements to GSL go undone because everyone has impostor syndrome. I work almost exclusively in C++ and Python (and I’m a physicist!) and I was able to contribute a new 1D interpolation routine that will be in 2.0. I looked at the existing code as a model and wrote the new routine accordingly. After submitting a patch I had to make some modifications to clean it up, but it was fine!

Re: [Help-gsl] GSL performance compared to C++ alternatives such as Armadillo
Armadillo would be faster. GSL would be more reliable and wider used. -Original Message- From: help-gsl-bounces+vsakharuk=hbk@gnu.org [mailto:help-gsl-bounces+vsakharuk=hbk@gnu.org] On Behalf Of Christopher Choi Sent: Monday, October 26, 2015 11:44 AM To: help-gsl@gnu.org Subject: [Help-gsl] GSL performance compared to C++ alternatives such as Armadillo Hello all, First of this is not a flame post, I would like to use GSL as linear algebra library for Neural Network training, so this would involve calculating hessian matrices, normal matrix and vector operations etc... I was curious as to how does GSL compares to C++ alternatives such as Armadillo, what are the pros and cons of using GSL as suppose to the alternatives? Additionally if someone could put me towards some benchmarks that would be great. Thanks Chris

Re: [Help-gsl] GSL 2D interpolation

Does anyone know how i can obtain a working update of gsl that includes "gsl_interp2d.h" and "gsl_spline2d.h"? I tried including these files and other dependencies as best as i could by hand but this yields, as probably expected, errors when linking in GCC (no problems in compiling). Regards,Lai For now you can work from the git: git clone git://git.savannah.gnu.org/gsl.git gsl-2.0 will hopefully be released within the week.
