matrix.ssc.hb-class {SparseM} | R Documentation |

## Class "matrix.ssc.hb"

### Description

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.ssc.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 s
sc format of the coefficient matrix, X.
`ia`

:- Object of class
`integer`

, 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.
