SOCAxis-class

R Documentation

The SOCAxis class.

Description

This class represents a second-order cone constraint for each row/column. It Assumes t is a vector the same length as X's rows (columns) for axis == 1 (2).

Usage

SOCAxis(t, X, axis, id = NA_integer_)

## S4 method for signature 'SOCAxis'

Arguments

`t`	The scalar part of the second-order constraint.
`X`	A matrix whose rows/columns are each a cone.
`axis`	The dimension across which to take the slice: `1` indicates rows, and `2` indicates columns.
`id`	(Optional) A numeric value representing the constraint ID.
`x`, `object`	A SOCAxis object.
`eq_constr`	A list of the equality constraints in the canonical problem.
`leq_constr`	A list of the inequality constraints in the canonical problem.
`dims`	A list with the dimensions of the conic constraints.
`solver`	A string representing the solver to be called.

Methods (by generic)

format_constr(SOCAxis): Format SOC constraints as inequalities for the solver.
num_cones(SOCAxis): The number of elementwise cones.
cone_sizes(SOCAxis): The dimensions of a single cone.
size(SOCAxis): The dimensions of the (elementwise) second-order cones.

Slots

t: The scalar part of the second-order constraint.
x_elems: A list containing X, a matrix whose rows/columns are each a cone.
axis: The dimension across which to take the slice: 1 indicates rows, and 2 indicates columns.
