s3only: Wappers for Sparse Matrices

Description

These functions are convenient wrappers for spam objects to classical matrix operations.

Usage

# S3 method for spam
eigen(x, …)

Arguments

x

matrix of class spam.

…

further arguments passed to or from other methods.

Depends on function…

Details

There is probably no point in fully defining methods here. Typically, these functions do not exploit sparsity structures. Hence, for very large matrices, warnings may be posted.
