R Documentation

The SOC class.

Description

This class represents a second-order cone constraint, i.e. \|x\|_2 \leq t.

Usage

SOC(t, X, axis = 2, id = NA_integer_)

Arguments

`t`	The scalar part of the second-order constraint.
`X`	A matrix whose rows/columns are each a cone.
`axis`	The dimension along which to slice: `1` indicates rows, and `2` indicates columns. The default is `2`.
`id`	(Optional) A numeric value representing the constraint ID.
`x`, `object`	A SOC 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)

residual(SOC): The residual of the second-order constraint.
get_data(SOC): Information needed to reconstruct the object aside from the args.
format_constr(SOC): Format SOC constraints as inequalities for the solver.
num_cones(SOC): The number of elementwise cones.
size(SOC): The number of entries in the combined cones.
cone_sizes(SOC): The dimensions of the second-order cones.
is_dcp(SOC): An SOC constraint is DCP if each of its arguments is affine.
is_dgp(SOC): Is the constraint DGP?
canonicalize(SOC): The canonicalization of the constraint.

Slots

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