NAME
sc::DiagSCMatrix - The SymmSCMatrix class is the abstract base class
for diagonal double valued matrices.
SYNOPSIS
#include <abstract.h> Inherits sc::DescribedClass. Inherited by sc::BlockedDiagSCMatrix, sc::DistDiagSCMatrix, sc::LocalDiagSCMatrix, and sc::ReplDiagSCMatrix. Public Member Functions DiagSCMatrix (const RefSCDimension &, SCMatrixKit *) Ref< SCMatrixKit > kit () const Return the SCMatrixKit used to create this object. virtual void save (StateOut &) Save and restore this in an implementation independent way. virtual void restore (StateIn &) virtual double maxabs () const Return the maximum absolute value element of this vector. virtual void randomize () Assign each element to a random number between -1 and 1. void assign (double val) Set all elements to val. void assign (const double *p) Assign element i, i to m[i]. void assign (DiagSCMatrix *d_a) Make this have the same elements as m. virtual void assign_val (double val) Overridden to implement the assign members. virtual void assign_p (const double *) virtual void assign_d (DiagSCMatrix *) virtual void convert (double *) const Like the assign member, but this writes values to the argument. virtual void convert (DiagSCMatrix *) Convert an SCDiagSCMatrix of a different specialization to this specialization and possibly accumulate the data. virtual void convert_accumulate (DiagSCMatrix *) virtual void scale (double) Multiply all elements by val. int n () const Return the dimension. virtual DiagSCMatrix * copy () Return a matrix with the same dimension and same elements. virtual DiagSCMatrix * clone () Return a matrix with the same dimension but uninitialized memory. RefSCDimension dim () const Return the dimension. virtual double get_element (int) const =0 Return or modify an element. virtual void set_element (int, double)=0 virtual void accumulate_element (int, double)=0 virtual void accumulate (const DiagSCMatrix *m)=0 Sum m into this. virtual double trace ()=0 Return the trace. virtual double determ_this ()=0 Return the determinant of this. this is overwritten. virtual double invert_this ()=0 Invert this. virtual void gen_invert_this ()=0 Do a generalized inversion of this. virtual void element_op (const Ref< SCElementOp > &)=0 Perform the element operation op on each element of this. virtual void element_op (const Ref< SCElementOp2 > &, DiagSCMatrix *)=0 virtual void element_op (const Ref< SCElementOp3 > &, DiagSCMatrix *, DiagSCMatrix *)=0 void print (std::ostream &o=ExEnv::out0()) const Print out the matrix. void print (const char *title=0, std::ostream &out=ExEnv::out0(), int=10) const virtual void vprint (const char *title=0, std::ostream &out=ExEnv::out0(), int=10) const Ref< MessageGrp > messagegrp () const Returns the message group used by the matrix kit. virtual Ref< SCMatrixSubblockIter > local_blocks (SCMatrixSubblockIter::Access)=0 Returns iterators for the local (rapidly accessible) blocks used in this matrix. virtual Ref< SCMatrixSubblockIter > all_blocks (SCMatrixSubblockIter::Access)=0 Returns iterators for the all blocks used in this matrix.

Detailed Description
The SymmSCMatrix class is the abstract base class for diagonal double
valued matrices.
Member Function Documentation
- void sc::DiagSCMatrix::assign (DiagSCMatrix * d_a) [inline]
- Make this have the same elements as m.
