Member Function Documentation

pure virtual

Evaluate generator function γ at (x, y).

pure virtual

Evaluate $\int \phi_i(x) D_x \gamma(x, y_{l}) dx$ for i ∈ is and points $y_{l}$ defined by pts. Store results in matrix at index (i,l).

pure virtual

Evaluate $\int \phi_j(y) D_y \gamma(x_{l}, y) dy$ for j ∈ is and points $x_{l}$ defined by pts. Store results in matrix at index (j,l).
