The function read.matrix.hb
returns a list of class
matrix.csc.hb
or matrix.ssc.hb
depending
on how the coefficient matrix is stored in the file
.
ra ra component of the csc or ssc format of the coefficient matrix, X.
ja ja component of the csc or ssc format of the coefficient matrix, X.
ia ia component of the csc or ssc format of the coefficient matrix, X.
rhs.ra ra component of the right-hand-side, y, if stored in csc or
ssc format; right-hand-side stored in dense vector or matrix otherwise.
rhs.ja ja component of the right-hand-side, y, if stored in csc or
ssc format; a null vector otherwise.
rhs.ia ia component of the right-hand-side, y, if stored in csc or
ssc format; a null vector otherwise.
xexactvector of the exact solutions, b, if they exist; a null vector otherwise.
guessvector of the initial guess of the solutions if they exist;
a null vector otherwise.
dimensiondimenson of the coefficient matrix, X.
rhs.dimdimenson of the right-hand-side, y.
rhs.modestorage mode of the right-hand-side; can be full storage or
same format as the coefficient matrix, for the moment the only allowed
mode is "F" for full, or dense mode.
The function model.matrix returns the X matrix of class matrix.csr.
The function model.response returns the y vector (or matrix).
The function model.guess returns the guess vector (or matrix).
The function model.xexact returns the xexact vector (or matrix).
