mfem::VectorArrayCoefficient Class Reference

Vector coefficient defined by an array of scalar coefficients. Coefficients that are not set will evaluate to zero in the vector. This object takes ownership of the array of coefficients inside it and deletes them at object destruction. More...

Detailed Description

Vector coefficient defined by an array of scalar coefficients. Coefficients that are not set will evaluate to zero in the vector. This object takes ownership of the array of coefficients inside it and deletes them at object destruction.

Definition at line 644 of file coefficient.hpp.

Constructor & Destructor Documentation

mfem::VectorArrayCoefficient::VectorArrayCoefficient ( int  dim)
explicit

Construct vector of dim coefficients. The actual coefficients still need to be added with Set().

Definition at line 339 of file coefficient.cpp.

mfem::VectorArrayCoefficient::~VectorArrayCoefficient ( )
virtual

Destroys vector coefficient.

Definition at line 365 of file coefficient.cpp.

Member Function Documentation
