bfieldtools.mesh_calculus.gradient

bfieldtools.mesh_calculus.gradient(vals, mesh, rotated=False)

Applies mesh (rotated) gradient matrix operator on vector that is defined in the vertex locations of the mesh.

Parameters

vals: Nv x 1 array of scalar data to compute the gradient of

mesh: Trimesh object describing the triangular mesh

rotated: boolean

If True, rotate gradient 90 degrees clockwise

Returns

ndarray (3, Ntris)

surface gradient of vals on each triangle
