eval_H

eval_H(R: MatrixBase, R_at_nodes: ndarray, exponents: ndarray)[source]

Evaluate all shape functions of an element.

Parameters:

  • R – matrix of shape (d, 1); symbolic reference space coordinates

  • R_at_nodes – array of shape (n, d); reference space coordinates at nodes

  • exponents – matrix of shape (n, d); exponents of powers of the shape functions

Returns:

symbolic matrix of shape (n, 1)
