Numerit's built-in dynamic-link library (DLL) interface provides the easiest way to use GSL. Although GSL was written in C, you don't have to be a C programmer in order to use it. All you need is a copy of the GSL DLL (see below how you can easily get one) and a simple declaration in your Numerit program for each GSL function you want to call. This declaration informs Numerit about the function's name and the number and types of its parameters and return value.
To make life even easier and help you use the GNU Scientific Library in the high-level Numerit programming environment right away, we have prepared a special interface package.

- An interface module with more than 1400 Numerit declarations of GSL functions and more than 100 Numerit declarations of GSL variables
that give you instant access to GSL from Numerit. The declarations are divided into categories according to
the GSL Reference Manual. These categories include:
Polynomial evaluation and roots
Special functions
Linear Algebra
Eigensystems
Fast Fourier Transforms
Quadratures
Random Numbers
Quasi-Random Sequences
Statistics
Histograms
Monte-Carlo Integration
Simulated Annealing
Differential Equations
Interpolation
Numerical Differentiation
Chebyshev Approximation
Discrete Hankel Transforms
Root Finding
Minimization
Least-Squares Fitting
Discrete Wavelet Transforms
And more...
- A collection of Numerit commented example programs that cover all the topics in the GSL Reference Manual. Besides demonstrating the use of GSL functions, these programs can be used as starting points to your own programs.
- A collection of DLLs with utilities that allow you to access GSL data objects that are not supported by Numerit. For example: copy GSL vectors and matrices from/to Numerit vectors and matrices, access the GSL integration workspace structure, copy null-terminated strings to Numerit strings, etc. Besides the usefulness of the utilities themselves, they can be used as examples to creating your own DLLs, as they are delivered with full source code and instructions how to compile them to DLLs using the free Borland C++ Compiler.
- A DLL that provides a simple but powerful mechanism to allow handling of GSL errors in Numerit. With this mechanism any error that is issued by a GSL function invokes Numerit's error handler.
Important Notes (read before you order):
- You should obtain a copy of the GSL DLL before you can use the Numerit-GSL Interface Package (see below how to do that). Without a copy of the GSL DLL the Numerit-GSL interface won't be of much use to you.
- Some GSL functions are not supported by the Numerit-GSL interface module: click here for details.
- The Numerit-GSL interface module does not include Numerit declarations for the routines in the BLAS library (these functions are actually not part of GSL but are used by it for low-level vector/matrix operations).
- You need a registered copy of Numerit Pro (see Download and Ordering). If you are already a registered user you must update your copy to the latest version (free).
- The Numerit-GSL interface module is intended to be used with Numerit Pro. If you are a user of the standard edition of Numerit, you can still use it, but you'll have to copy it (or parts of it) to each program that needs to call GSL functions.
- The Numerit-GSL interface has been tested with GSL version 1.8.
- The Numerit-GSL Interface Package comes as a zip file. You must be able to open zip files in order to extract the package's files.
- The Numerit-GSL Interface Package User's Guide comes as a PDF file and requires the
Adobe Reader. If you don't already have the Adobe Reader you can get if for free from
the Adobe Reader Download Page.
You can download the User's Guide from the following link (it also comes with the package): The Numerit-GSL Interface Package User's Guide. - Please read The Numerit-GSL Interface Package License Agreement.
To install and run the demo you should do the following:
- Download and install NumRun (1.06 MB).
- Download the GSL Binaries file. Extract the two DLL files - libgsl.dll and libgslcblas.dll to any directory of your choice. You can also download the GSL Documentation file that contains the GSL Reference Manual.
- Download Numerit-GSL-Demo.zip and extract its content (.nex files and DLLs) to the same directory as the GSL DLLs.
- Launch NumRun, then open any Numerit program (.nex) and click the Run button (or press F9).
