flcontour2mesh
Purpose
flcontour2mesh
Create boundary mesh from contour data.
Syntax
Description
m = flcontour2mesh(c)
m = flcontour2mesh(c) creates a boundary mesh m with fields m.p and m.e from
the contour data c. The contour matrix c is a two-row matrix of contour lines. Each
contiguous drawing segment contains the value of the contour, the number of (x,y)
drawing pairs, and the pairs themselves. The segments are appended end-to-end as
c = [level1 x1 x2 x3 ... level2 x2 x2 x3 ...;
pairs1 y1 y2 y3 ... pairs2 y2 y2 y3 ...]
The contour matrix format is used by the COMSOL Script or MATLAB function
contourc.
By using the contour matrix format, you can convert geometry data defined by a
point set, to a COMSOL Multiphysics geometry object. Firstly, define a contour
matrix c corresponding to your point set and use flcontour2mesh to convert the
contour matrix c to a 2D boundary mesh m. Then, use flmesh2spline to convert
the mesh object m to a curve2 object.
Examples
Create a mesh from contour data.
[x,y] = meshgrid(linspace(-3,3,50));
z = (x.^2+y.^2).*exp(-x.^2-y.^2)+cos(y)+sin(x);
