Member Function Documentation

static const char* fei::MatrixTraits< LinearSystemCore >::typeName ( )

inlinestatic

Return a string type-name for the underlying matrix

Definition at line 25 of file fei_MatrixTraits_LinSysCore.hpp.

static int fei::MatrixTraits< LinearSystemCore >::setValues ( LinearSystemCore *  lsc, double  scalar  )

inlinestatic

Set a specified scalar value throughout the matrix.

Definition at line 40 of file fei_MatrixTraits_LinSysCore.hpp.

static int fei::MatrixTraits< LinearSystemCore >::getNumLocalRows ( LinearSystemCore *  lsc, int &  numRows  )

inlinestatic

Query the number of rows. This is expected to be the number of rows on the local processor.

Definition at line 48 of file fei_MatrixTraits_LinSysCore.hpp.

static int fei::MatrixTraits< LinearSystemCore >::getRowLength ( LinearSystemCore *  lsc, int  row, int &  length  )

inlinestatic

Given a global (zero-based) row number, query the length of that row.

Definition at line 56 of file fei_MatrixTraits_LinSysCore.hpp.

static int fei::MatrixTraits< LinearSystemCore >::copyOutRow ( LinearSystemCore *  lsc, int  row, int  len, double *  coefs, int *  indices  )

inlinestatic

Given a global (zero-based) row number, pass out a copy of the contents of that row.

Parameters

lsc
row
len	Length of the user-allocated arrays coefs and indices.
coefs	User-allocated array which will hold matrix coefficients on output.
indices	User-allocated array which will hold column-indices on output.

Returns

error-code 0 if successful. Non-zero return-value may indicate that the specified row is not locally owned.

Definition at line 73 of file fei_MatrixTraits_LinSysCore.hpp.

static int fei::MatrixTraits< LinearSystemCore >::putValuesIn ( LinearSystemCore *  lsc, int  numRows, const int *  rows, int  numCols, const int *  cols, const double *const *  values, bool  sum_into  )

inlinestatic

Sum a C-style table of coefficient data into the underlying matrix.

Definition at line 82 of file fei_MatrixTraits_LinSysCore.hpp.

static int fei::MatrixTraits< LinearSystemCore >::globalAssemble ( LinearSystemCore *  lsc )

inlinestatic

Perform any necessary internal communications/synchronizations or other operations appropriate at end of data input. For some implementations this will be a no-op, so this "default implementation" will return 0.

Definition at line 102 of file fei_MatrixTraits_LinSysCore.hpp.

static int fei::MatrixTraits< LinearSystemCore >::matvec ( LinearSystemCore *  lsc, fei::Vector *  x, fei::Vector *  y  )

inlinestatic

Compute the matrix-vector product y = A*x
