R: Class "matrix.ssc.hb"

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.
