Overridden from MatrixSymInitDiag.

These function call the corresponding functions on B_RR_ptr()# and then call the equivalent of: {verbatim} MatrixHessianSuperBasic::initialize( this->B_RR_ptr()->rows(),this->B_RR_ptr()->cols() ,NULL,NULL,NULL ,this->B_RR_ptr() ,this->B_RX_ptr(),this->B_RX_trans() ,this->B_XX_ptr() ); {verbatim}

Member Function Documentation

void ConstrainedOptPack::MatrixHessianSuperBasicInitDiagonal::initialize ( size_type  n,
size_type  n_R,
const size_type  i_x_free[],
const size_type  i_x_fixed[],
const EBounds  bnd_fixed[],
const B_RR_ptr_t B_RR_ptr,
const B_RX_ptr_t B_RX_ptr,
BLAS_Cpp::Transp  B_RX_trans,
const B_XX_ptr_t B_XX_ptr 

Initialize the matrix and require B_RR to support MatrixSymInitDiag#.

Preconditions:{itemize} dynamic_cast<MatrixSymInitDiag*>(const_cast<MatrixSymWithOpFactorized*>(B_RR_ptr.get())) != NULL# {itemize}

This overridden function is a little bit of a hack but it is better than the alternatives that I could think of. What is important is that the MatrixSymInitDiag# interface for this class will be supported as long as this function executes succesfully on initialization. This is far better than waiting until later when dynamic casting would be done and failed. We need to catch any mistakes right away.

In this manner we will have given up some compile-time checking but the run-time check will be very good.
