int ToMatlab(const CString& sFilename) const

Writes mesh structure to a matlab file containing three vectors:

xTri X-points. yTri Y-points. Tri Triangles defined as an (ntriangles x 3) matrix. Thus each row defines a triangle using three indices pointing to the point-vectors.

Parameters:

sFilename - The filename to be written. The file is overwritten if it already exists.

Returns:

Zero on succes, non-zero if the mesh is empty.
