MATLAB at NERSC

MATLAB is a high-performance language for technical computing. It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation. MATLAB features a family of add-on application-specific solutions called toolboxes. Toolboxes are comprehensive collections of MATLAB functions (M-files) that extend the MATLAB environment to solve particular classes of problems. NERSC MATLAB includes six toolboxes that support applications involving neural networks (nnet), optimization (optim), partial differential equation (pde),signal processing (signal), spline (splines) and statistics (stats).

The name MATLAB stands for matrix laboratory. MATLAB was originally written to provide easy access to matrix software developed by the LINPACK and EISPACK projects. Today, MATLAB engines incorporate the LAPACK and BLAS libraries, embedding the state of the art in software for matrix computation.

To use the default version of MATLAB, include the line:

% module load matlab

Jacquard Interactive Matlab Users

The default interactive virtual memory limit is not large enough on the interactive nodes of Jacquard to run matlab. You will be able to run matlab by increasing the virtual memory limit to the the hard limit of 2097152 kbytes by typing in (bash shell or ksh):

% ulimit -v 2097152

% limit vmemoryuse 2097152

Davinci Matlab Users

The SGI platform is not supported by the vendor with this version of MATLAB. It is available in x86 emulation mode only. Please use the following command to invoke matlab:

% matlab -glnx86
