SOCAxis-class function

The SOCAxis class.

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). class

SOCAxis(t, X, axis, 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 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.
