14.2.35 Class SymRangedVariable¶
Defines a ranged variable.
Since this actually defines one variable with two inequalities, there will be two dual variables (slx and sux) corresponding to the lower and upper bounds. When asked for the dual solution, this variable will return (y=slx-sux), but in some cases this is not enough (the individual dual variables may be required by e.g. a certificate).
BaseVariable.Antidiag – Return the antidiagonal of a square variable matrix.
BaseVariable.AsExpr – Create an expression corresponding to the variable object.
BaseVariable.Diag – Return the diagonal of a square variable matrix.
BaseVariable.Dual – Get the dual solution value of the variable.
BaseVariable.Eval – Evaluate the expression and push the result onto the work stack.
BaseVariable.FromTril – Convert from a trilinear representation into a square variable.
BaseVariable.GetDim – Return the d’th dimension in the expression.
BaseVariable.GetModel – Get the Model object that the variable belongs to.
BaseVariable.GetND – Get the number of dimensions in the variable shape.
BaseVariable.GetShape – Get the variable shape.
BaseVariable.GetSize – Get the total number of elements in the variable.
BaseVariable.Index – Return a variable slice of size 1 corresponding to a single element in the variable object..
BaseVariable.Level – Get the primal solution value of the variable.
BaseVariable.MakeContinuous – Drop integrality constraints on the variable, if any.
BaseVariable.MakeInteger – Apply integrality constraints on the variable. Has no effect on elements of semidefinite matrix variables.
BaseVariable.Pick – Create a one-dimensional variable by picking a list of indexes from this variable.
BaseVariable.Reshape – Reshape the variable. The new shape must have the same total size as the current.
BaseVariable.SetLevel – Input solution values for this variable
BaseVariable.Slice – Create a slice variable by picking a range of indexes for each variable dimension.
BaseVariable.ToString – Create a string representation of the variable.
BaseVariable.Transpose – Transpose the variable.
BaseVariable.Tril – Convert from a square variable to a trilinear representation.
ModelVariable.Remove – Remove the variable from the model.
