desc.basis.PowerSeries.evaluate

PowerSeries.evaluate(grid, derivatives=array([0, 0, 0]), modes=None)Source

Evaluate basis functions at specified nodes.

Parameters:

• grid (Grid or ndarray of float, size(num_nodes,3)) – Node coordinates, in (rho,theta,zeta).

• derivatives (ndarray of int, shape(num_derivatives,3)) – Order of derivatives to compute in (rho,theta,zeta).

• modes (ndarray of in, shape(num_modes,3), optional) – Basis modes to evaluate (if None, full basis is used)

Returns:

y (ndarray, shape(num_nodes,num_modes)) – basis functions evaluated at nodes
