mcdisplay-matlab - mcstas Graphical display of simulations using Matlab/Octave
Contents
Description
The mcdisplay-matlab front-end is a graphical debugging tool. It presents a schematic drawing of the
instrument definition, showing the position of the components and the paths of the simulated neutrons
through the instrument. It is thus very useful for debugging a simulation, for example to spot
components in the wrong position or to find out where neutrons are getting lost. To use the
mcdisplay-matlab front-end with a simulation, run it as follows: mcdisplay INSTR args... where INSTR is
the name of either the instrument source INSTR.instr or the simulation program INSTR.out generated with
mcstas, and args are the normal command line arguments for the simulation, as for mcrun. The -h option
will list valid options.
The default plotting backend is mxdisplay-pyqtgraph, but there exists a number of additional plotters
such as mxdisplay-matplotlib, mxdisplay-webgl-classic (using WebGL), mxdisplay-webgl (using WebGL and
NodeJS), mxdisplay-matlab (using Matlab or Octave). This is the Matlab/Octave plotting tool.
