gsl

问题 I cross compiled gsl fro android using arm-linux-androideabi . When I dynamically loaded this library in android-studio , it gave me error. can not locate symbol cblas_sdsdot. I ran nm command on gsl and got U cblas_sdsdot Then I ran nm command on gslcblas and got 000002645 T cblas_sdsdot. I also loaded gslcblas.so before gsl.so but still I am getting the error. Any suggestion to get rid of this problem? Thanks 来源： https://stackoverflow.com/questions/30727709/gsl-nm-outputs-undefined-symbol-u

问题 Context: I have an application that makes heavy use of the GSL library and its Ruby bindings. I'd like to deploy the app to Heroku. I'm very new to programming in general, much less deployment, and Heroku is very simple to use, especially for Rails apps. I have GSL installed on my laptop. I am using the 'gsl' gem. The Problem: The gem requires that the GSL library already be installed. GSL is not already installed in the Heroku environment. So, unsurprisingly, I get this error from Heroku

问题 I'm trying make a shared library in c++ implementing tools for Fermi gases. I'm using the GSL library to solve a function numerically and my code runs without a problem without when running as a script, but when trying to convert it to a shared library and classes I encounter problems. I've seen similar questions: Q1 Q2 Q3 I'm fairly new to c++-programming and cannot seem to adapt the different answers to my problem. Probably since I do not quite understand the answers. My code is: /* Define

问题 I am trying to get Xcode 5.1.1 to find the headers of GSL. My ideal solution would be one that would allow me to access these headers on all future projects with no extra work (automagically if you will). Most instructions seem to say to add the library path under the project's Build Setting -> Search Path section, however, my project does not seem to have a library or header option there. I have also tried to use the Link Binary with Libraries under the Build Phases tab, but /usr/local

问题 I'm attempting to install the mvabund package from github here on Windows 10 in R 3.5.1 (The github version has functions not yet available in the cran versions.): https://github.com/aliceyiwang/mvabund I've installed Rtools, using the instructions for another package here: https://cran.r-project.org/web/packages/dynr/vignettes/InstallationForUsers.pdf and all the checks there indicate that GSL and RTools are installed properly. However, when I try to install the package with devtools, it

问题 Can somebody help me figure out how to do this operation. I'm looking at the documentation, but its been so long since I've had to do any linear algebra type stuff I'm a little lost. I have a 14x14 complex matrix called Y and a complex vector called I. I need to multiply them and set the result to a complex vector named IL. So far I have figured out that I need to use: gsl_blas_zgemv (CBLAS_TRANSPOSE_t TransA, const gsl_complex alpha, const gsl_matrix_complex * A, const gsl_vector_complex * x

问题 I am currently using gsl_odeiv2 methods inside my classes to solve differential equations. But because of the well known memberfunction problem I can not define my ode-system inside the class. I am currently using a workaround: I define my ode in a global namespace: ODE.hpp: #include "EoS.hpp" #include <gsl/gsl_math.h> #include <gsl/gsl_errno.h> namespace ODEs { struct tov_eq_params {EoS *eos;}; int tov_eq(double, const double *, double *, void *); } ODE.cpp: namespace ODEs { int tov_eq

问题 I try to install gsl gem for Ruby but it doesn't work. i have a matrix_complex.o error. So is there a solution to install gsl for netbeans ? or is there a fonction quantile in an other library? Any help would be appreciated. stagiaire@stagiaire-desktop:~$ sudo gem install -v=1.14.7 gsl Building native extensions. This could take a while...

问题 my program manipulates STL vectors of integers but, from time to time, I need to calculate a few statistics on them. Therefore I use the GSL functions . To avoid copying the STL vector into a GSL vector, I create a GSL vector view , and give it to the GSL functions, as in this piece of code: #include <iostream> #include <vector> #include <gsl/gsl_vector.h> #include <gsl/gsl_statistics.h> using namespace std; int main( int argc, char* argv[] ) { vector<int> stl_v; for( int i=0; i<5; ++i ) stl
