To perform a volume integral of a patched object in MATLAB, you can use the integral2
function. Here is an example of how you can do this for a 3D object defined by a set of points and faces:
main.m642 chars16 lines
In this example, vertices
and faces
define the geometry of the object, and f
is the function you want to integrate over the object. inpolyhedron
is a helper function that checks if a point is inside the patch object. Finally, integral2
is used with a custom function that checks if a point is inside the object and evaluates the function f
at that point.
Ensure you have the inpolyhedron
function available in your MATLAB path. You may need to download it from the MATLAB File Exchange.
