matrix.csc.hb-class function

Class "matrix.csc.hb" - Column Compressed Sparse Matrices stored in Harwell-Boeing Format

A class consisting 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.

Methods

• model.matrix: signature(object = "matrix.csc.hb"): ...
• show: signature(object = "matrix.csc.hb"): show() the object, notably also when auto-printing.
