Detailed Description

These allow nonmember functions to act like virtual functions. If any of these methods on the subclasses are not implemented for a particular set of matrix arguments, then the exception AbstractLinAlgPack::MatrixOp::MethodNotImplemented is thrown. This will not happen as long as a compatible (vector spaces are compatible) lhs matrix argument is passed in and dynamic_cast<MultiVectorMatrix*>(lhs) != NULL.

Function Documentation

void AbstractLinAlgPack::Mt_S (  MatrixOp *  mwo_lhs,
value_type  alpha
) 
 

mwo_lhs *= alpha.

If alpha == 0.0 then mwo_lhs->zero_out() will be called, otherwise mwo_lhs->Mt_S(alpha) will be called. If alpha == 1.0 then nothing is done.

void AbstractLinAlgPack::Mp_StM (  MatrixOp *  mwo_lhs,
value_type  alpha,
const MatrixOp &  M_rhs,
BLAS_Cpp::Transp  trans_rhs
) 
 

mwo_lhs += alpha * op(M_rhs) (BLAS xAXPY).

Entry point for (poor man's) multiple dispatch.

This method first calls M_rhs->Mp_StM(mwo_lhs,alpha,trans_rhs) to give the rhs argument a chance to implement the operation. If M_rhs->Mp_StM(...) returns false, then mwo_lhs->Mp_StM(alpha,*this,trans_rhs) is called to give the lhs matrix argument a chance to implement the method. If mwo_lhs->Mp_StM(...) returns false, then an attempt to perform a dynamic cast the lhs matrix argument to MultiVectorMutable is attempted. If this cast failes, then an exception is thrown.

) 
 

This method first calls mwo_rhs1.Mp_StMtM(...) to perform the opeation. If mwo_rhs1.Mp_StMtM(...) returns false, then mwo_rhs2.Mp_StMtM(...) is called. If mwo_rhs2.Mp_StMtM(...) returns false, then mwo_lhs.Mp_StMtM(...) is called.

As a last resort, the function attempts to cast dynamic_cast<MultiVectorMutable*>(mwo_lhs). If this dynamic cast fails, the this function throws an exception. Otherwise, the operation is implemented in terms of Vp_StMtV().

MatrixSymOp *  sym_lhs
) 
 

symwo_lhs += alpha*op(mwo_rhs)*op(mwo_rhs') + beta*symwo_lhs

The default implementation returns false and does nothing.
