MATLAB (MATrix LABoratory) is a popular, powerful, general-purpose system or environment for matrix algebra calculations and many other more specific computations and applications in Biology, Aerospace, Finance, data acquisition, etc. MATLAB may be used interactively or in batch. In addition, it supports a wide array of graphical applications, ranging from bar charts, line and surface plots to volumetric rendering.<\/p>\n

To invoke MATLAB on the SCC, load the desired module version, then type:<\/p>\n This should bring up MATLAB in its own separate window with the Command Window<\/b> active and the On clients without xterm or if graphics are not needed, you can start MATLAB with graphics disabled:<\/p>\n To close either version of the MATLAB session, enter See MATLAB Batch Jobs on the SCC<\/a>.<\/p>\n The large majority of compute nodes on the SCC use Intel CPUs, with the remainder using AMD CPUs. For information on specific nodes, refer to the Technical Summary<\/a> page. When running Matlab version 2022a or newer on AMD CPUs, the underlying libraries for linear algebra (BLAS and LAPACK) can be changed from the default implementation (the Intel MKL libraries) for ones optimized by AMD for their CPUs. This may improve performance of your Matlab code. The change is done by setting a pair of environment variables, either interactively in a terminal before starting Matlab or in a batch job:<\/p>\n To get started with MATLAB, you can watch our video Using MATLAB on the SCC<\/a>.
