33// Control bits codes for GetRow, GetCol, RestoreRow, RestoreCol
34//
35// LoadOnEntry:
36// Load data into MatrixRow or Col dummy array under GetRow or GetCol
37// StoreOnExit:
38// Restore data to original matrix under RestoreRow or RestoreCol
39// DirectPart:
40// Load or restore only part directly stored; must be set with StoreOnExit
41// Still have decide how to handle this with symmetric
42// StoreHere:
43// used in columns only - store data at supplied storage address;
44// used for GetCol, NextCol & RestoreCol. No need to fill out zeros
45// HaveStore:
46// dummy array has been assigned (internal use only).
47
48// For symmetric matrices, treat columns as rows unless StoreHere is set;
49// then stick to columns as this will give better performance for doing
50// inverses
51
52// How components are used:
53
54// Use rows wherever possible in preference to columns
55
56// Columns without StoreHere are used in in-exact transpose, sum column,
57// multiply a column vector, and maybe in future access to column,
58// additional multiply functions, add transpose
59
60// Columns with StoreHere are used in exact transpose (not symmetric matrices
61// or vectors, load only)
62
63// Columns with MatrixColX (Store to full column) are used in inverse and solve
64
65// Functions required for each matrix class
66
67// GetRow(MatrixRowCol& mrc)
68// GetCol(MatrixRowCol& mrc)

73// NextRow(MatrixRowCol& mrc)

79// Assume cannot have both !DirectPart && StoreHere for MatrixRowCol routines
80
81
82// Default NextRow and NextCol:
