Public Member Functions | |
MatrixRestrictedCoefficient (MatrixCoefficient &mc, Array< int > &attr) | |
Construct with a parent matrix coefficient and an array of zeros and ones representing the attributes for which this coefficient should be active. | |
void | SetTime (real_t t) |
Set the time for internally stored coefficients. | |
virtual void | Eval (DenseMatrix &K, ElementTransformation &T, const IntegrationPoint &ip) |
Evaluate the matrix coefficient at ip. | |
Public Member Functions inherited from mfem::MatrixCoefficient | |
MatrixCoefficient (int dim, bool symm=false) | |
Construct a dim x dim matrix coefficient. | |
MatrixCoefficient (int h, int w, bool symm=false) | |
Construct a h x w matrix coefficient. | |
real_t | GetTime () |
Get the time for time dependent coefficients. | |
int | GetHeight () const |
Get the height of the matrix. | |
int | GetWidth () const |
Get the width of the matrix. | |
int | GetVDim () const |
