14.2.7 Class ConicVariable

mosek.fusion.ConicVariable

This class represents a conic variable of the form

\[x \in \K\]

where \(\K\) is a cone. Then class is never explicitly instantiated, but is created using Model.variable by specifying a conic domain.

Note that a conic variable in Fusion is always dense in the sense that all member variables are created in the underlying optimization problem immediately.

Implements:

ModelVariable

Members:

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 associated model.

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.transpose – Transpose the variable.

BaseVariable.tril – Convert from a square variable to a trilinear representation.

ConicVariable.toString – Create a string representation of the variable.

ModelVariable.remove – Remove the variable from the model.

ConicVariable.toString

String toString()

Create a string representation of the variable.

Return:

(String)
