The experimental pict

Matlab toolbox contains the siMesh class which allows to use simplices meshes generated from gmsh (in dimension 2 or 3) or from an hypercube triangulation (in any dimension).

Matlab / Mesh / fc_simesh/ Tested on

This toolbox was only tested on Ubuntu 22.04.1 with Matlab R2022a.

Matlab / Mesh / fc_simesh/ Installation

One just has to get/download the install file mfc_simesh_install.m Thereafter, one run it under Matlab. This command download, extract and configure the pict toolbox and all the required required toolboxes in the current directory.

For example, to install this toolbox in ~/Matlab directory, one has to copy the file mfc_simesh_install.m in the ~/Matlab directory. Then in a Matlab terminal run the following commands

Matlab Console

>> cd ~/Matlab 
>> mfc_simesh_install

There is the output of the mfc_simesh_install command on a Linux computer:

   See ~/Matlab/mfc_simesh_set.m

The complete toolbox (i.e. with all the other needed toolboxes) is stored in the directory ~/Matlab/fc-simesh-full and, for each Matlab session, one have to set the toolbox by:

Matlab Console

>> addpath(’~/Matlab/fc-simesh-full/fc-simesh-0.4.5’) 
>> fc_simesh.init()

If it’s the first time the fc_simesh.init() function is used, then its output is

For uninstalling, one just have to delete directory

~/Matlab/fc-simesh-full

To quickly test this toolbox , one can run one of the examples located in the directory +fc_simesh/+demos. For example, runs

Matlab Console

>> fc_simesh.demos.feval2D01()

Matlab Console

>> fc_simesh.demos.plot2D()

or the complete demo (without graphics, testing various MSH file format, take a long time)

Matlab Console

>> fc_simesh.demos.alldemos()

To use another gmsh binary, one can use the fc_oogmsh.configure Matlab function as

Matlab Console

>> fc_oogmsh.configure(’gmsh_bin’,’<PATH TO>/gmsh’)

where <PATH TO> will be replaced by the path to the gmsh binary. See

for more details.
