In ROI: R Optimization Infrastructure

Canonicalize the Quadraric Term

Description

Canonicalize the quadraric term of a quadratic constraint. Objects from the following classes can be canonicalized: "NULL", "numeric", "matrix", "simple_triplet_matrix" and "list".

Usage

as.Q_term(x, ...)

## S3 method for class 'list'
as.Q_term(x, ...)

## S3 method for class 'numeric'
as.Q_term(x, ...)

## S3 method for class 'matrix'
as.Q_term(x, ...)

## S3 method for class 'simple_triplet_matrix'
as.Q_term(x, ...)

## S3 method for class ''NULL''
as.Q_term(x, ...)

Arguments

x	an R object.
...	further arguments

Details

In the case of lists "as.Q_term" is applied to every element of the list, for NULL one can supply the optional arguments "nrow" and "ncol" which will create a "simple_triplet_zero_matrix" with the specified dimension.

Value

an object of class "simple_triplet_matrix"
