Public Member Functions | |
VectorArrayCoefficient (int dim) | |
Construct vector of dim coefficients. The actual coefficients still need to be added with Set(). More... | |
Coefficient * | GetCoeff (int i) |
Returns i'th coefficient. More... | |
Coefficient ** | GetCoeffs () |
Returns the entire array of coefficients. More... | |
void | Set (int i, Coefficient *c, bool own=true) |
Sets coefficient in the vector. More... | |
double | Eval (int i, ElementTransformation &T, const IntegrationPoint &ip) |
virtual void | Eval (Vector &V, ElementTransformation &T, const IntegrationPoint &ip) |
Evaluate the coefficient. Each element of vector V comes from the associated array of scalar coefficients. More... | |
virtual | ~VectorArrayCoefficient () |
Destroys vector coefficient. More... | |
