gsl

I got a problem while installing the GNU Scientific Library (gsl). I put the package on my desktop, and did "./configure", "make", and "sudo make install", according to the document included. I checked the /usr/local/include directory, there is a newly created "gsl" folder in there. But When I tried to use the functions provided by the library, the "undefined reference to 'gsl_sf_beta_inc'" error occurred. Here is my code. #include <stdio.h> #include <gsl/gsl_sf_gamma.h> int main (void) { double a = 20; double b = 1000; double x = 0.5; double result = gsl_sf_beta_inc(a, b, x); printf("%f/d",

I am trying to port a MATLAB program to C++. And I want to implement a left matrix division between a matrix A and a column vector B . A is an m-by-n matrix with m is not equal to n and B is a column vector with m components. And I want the result X = A\B is the solution in the least squares sense to the under- or overdetermined system of equations AX = B . In other words, X minimizes norm(A*X - B) , the length of the vector AX - B . That means I want it has the same result as the A\B in MATLAB. I want to implement this feature in GSL-GNU (GNU Science Library) and I don't know too much about

I found this site http://gnuwin32.sourceforge.net/packages/gsl.htm from which I downloaded "Complete package, except sources" and installed. But this is only 6.2MB large, which I find to be very small. Is this correct? I would be happy to get some help with this. I don't understand why this has to be so difficult. 回答1: I am beginner as well, but I just managed to have it work on windows 8 with codeblock 12.11. installing gsl from

I use gsl. After I compiled my .cpp file and run it, I faced with below error: error while loading shared libraries: libgsl.so.0: cannot open shared object file: No such file or directory I found same as this problem in: https://groups.google.com/forum/#!topic/cortex_var/6vluX7pP0Sk & Linux error while loading shared libraries: cannot open shared object file: No such file or directory & http://www.gnu.org/software/gsl/manual/html_node/Shared-Libraries.html And I have done as in the above links wrote but the error is still remained. Can anyone help me? To make it work do the following steps

Although most of the code has now been redesigned from scratch for this purpose, the generation of random numbers is still at its core. Thus, bad performance of the random number generator (RNG) affects very badly the overall performance of the program. I wrote some code lines (see below) to show the problem I am facing without much verbosity. The problem is the following: everytime the number of threads nt increases, the performance gets singnificantly worse.

If I am not mistaken the “module” I mention is equivalent to a C library―at least for the concerns of my problem. On Debian I am trying to create a Python module with C, which in turn uses the GSL. The following Makefile successfully compiles it: CC = gcc -Wall -fPIC -O3 NAME = meinzeug matrizenwuerfler: $(SRC) $(CC) -o $(NAME).o -I/usr/lib/python2.5/site-packages/numpy/core/include -I/usr/include/python2.5 -c $(NAME

I have installed MinGW and MSYS on Microsoft Windows (64bit), inside directory C:\MinGW (MSYS directory is C:\MinGW\msys\1.0 ). I have downloaded the latest GNU Scientific Library ( GNU GSL ) package from the official ftp . I have used MSYS to perform configure and make successfully as described in the INSTALL file in the GSL package. That means, in the MSYS command-line interface, in the MSYS home directory, I have inserted: $ ./configure $ make $ make install This produces a local directory under the MSYS directory ( C:\MinGW\msys\1.0 ) including the directories bin , include , lib , and

I have 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. I've set the Windows system environment variables LIB_GSL (as "C:/R/local323" ) and PATHS (as "C:/RTools/bin/", "C:/RTools/mingw_64/bin", "C:/R/R-3.5.1/bin" ) I also run the following code in R
