Arguments

x, object

A '>Constraint object.

tolerance

The tolerance for checking if the constraint is violated.

value

A numeric scalar, vector, or matrix.

Methods (by generic)

  • dim: The dimensions of the constrained expression.

  • size: The size of the constrained expression.

  • is_real: Is the constraint real?

  • is_imag: Is the constraint imaginary?

  • is_complex: Is the constraint complex?

  • is_dcp: Is the constraint DCP?

  • is_dgp: Is the constraint DGP?

  • residual: The residual of a constraint

  • violation: The violation of a constraint.

  • constr_value: The value of a constraint.

  • get_data: Information needed to reconstruct the object aside from the args.

  • dual_value: The dual values of a constraint.

  • dual_value<-: Replaces the dual values of a constraint..

  • size: The size of the constrained expression.
