grad

compas.numerical.grad(V, F, rtype='array')

Construct the gradient operator of a trianglular mesh.

Parameters

• V (array) – Vertex coordinates of the mesh.

• F (array) – Face vertex indices of the mesh.

• rtype ({‘array’, ‘csc’, ‘csr’, ‘coo’, ‘list’}) – Format of the result.

Returns

array-like – Depending on rtype return type.

Notes

The gradient operator is fully determined by the connectivity of the mesh and the coordinate difference vectors associated with the edges
