virtual void right_multiply(const DenseMatrixBase< T > &M3) libmesh_override
Performs the operation: (*this) <- (*this) * M3.
The libMesh namespace provides an interface to certain functionality in the library.
Defines a dense submatrix for use in Finite Element-type computations.
Defines an abstract dense matrix base class for use in Finite Element-type computations.
virtual void left_multiply(const DenseMatrixBase< T > &M2) libmesh_override
Performs the operation: (*this) <- M2 * (*this)
