[Gmsh] using load_gmsh4.m

[Jose Paulo Moitinho de Almeida]

Hello

In the function declaration 'filename' is an argument which when you call the 
function gets replaced by whatever name you use. If you use a constant string 
as a variable you get a syntax error.

So, after putting 'filename' back in the beginning of the function definition 
(without quotes) you should just write at the matlab command prompt ">>".

m=load_gmsh4('cube');

and it should work. Inside the call the content of variable 'filename' becomes 
'cube'.

Notes:
- gmsh files normally have the extension .msh 
If you change the extension you have to add the extension to the name in the 
function call;
- you can use whatever name you like for the variable that is returned. 
For example
my_mesh=load_gmsh4('cube');
or even load two meshes simultaneously
my2D = load_gmsh4('square.msh');
my3D = load_gmsh4('cube.msh');

Hope this helps. Good luck

ZP
