◆ eval()
|
pure virtual |
Evaluate generator function γ at (x, y).
Implemented in TLaplaceDLPGenFn< T_ansatzsp, T_testsp, T_value >, TLaplaceSLPGenFn< T_ansatzsp, T_testsp, T_value >, THelmholtzDLPGenFn< T_ansatzsp, T_testsp, T_value >, THelmholtzSLPGenFn< T_ansatzsp, T_testsp, T_value >, and TExpGenFn< T_ansatzsp, T_testsp, T_value >.
◆ integrate_dx()
|
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).
Implemented in TPermHCAGeneratorFn< T_value >.
◆ integrate_dy()
|
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).
Implemented in TPermHCAGeneratorFn< T_value >.
