A new class consists of the coefficient matrix and
the right-hand-side of a linear system of equations,
initial guess of the solution and the exact solutions if they exist stored
in external files using the Harwell-Boeing format.
Objects from the Class
Objects can be created by calls of the form new("matrix.csc.hb", ...).
Slots
ra:
Object of class numeric, ra component of the csc or ssc format of the coefficient matrix, X.
ja:
Object of class integer, ja component of the csc or ssc format of the coefficient matrix, X.
ia:
Object of class numeric, ia component of the csc or ssc format of the coefficient matrix, X.
rhs.ra:
Object of class numeric, 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.
guess:
Object of class numeric or NULL vector of the initial guess of the solutions if they exist;
a null vector otherwise.
xexact:
Object of class numeric or NULL vector of the exact solutions, b, if they exist; a null vector otherwise.
dimension:
Object of class integer, dimenson of the coefficient matrix, X.
rhs.dim:
Object of class integer, dimenson of the right-hand-side, y.
rhs.mode:
Object of class character or NULL storage mode of the right-hand-side; can be full storage or
same format as the coefficient matrix.
