helper.cvx_kron

Kronecker product for CVXPY objects.

Functions

cvx_kron(expr_1, expr_2)

Compute Kronecker product between CVXPY objects.
helper.cvx_kron.cvx_kron(expr_1, expr_2)

Compute Kronecker product between CVXPY objects.

By default, CVXPY does not support taking the Kronecker product when the argument on the left is equal to a CVXPY object and the object on the right is equal to a numpy object.

At most one of expr_1 and b may be CVXPY Variable objects.

Kudos to Riley J. Murray for this function [1]

Riley J Murray. PR: have kron support non-constant expressions in either argument from CXPY: a python-embedded modeling language for convex optimization problems. https://github.com/cvxpy/cvxpy/issues/457#issue-309891424.

Parameters:

  • expr_1 (numpy.ndarray | cvxpy.expressions.expression.Expression) – 2D numpy ndarray, or a CVXPY Variable with expr_1.ndim == 2

  • expr_2 (numpy.ndarray | cvxpy.expressions.expression.Expression) – 2D numpy ndarray, or a CVXPY Variable with expr_2.ndim == 2

Returns:

The tensor product of two CVXPY expressions.

Return type:

cvxpy.expressions.expression.Expression
