secondordercone — Create a second-order cone constraint descriptor for coneprog.

secondordercone(A,b,d,gamma) creates a descriptor for norm(A*x + b) <= d'*x + gamma.

Syntax

secondordercone(A,b,d,gamma)

How secondordercone works

  • A must be a nonempty numeric matrix.
  • b must match the rows of A; d must match the columns of A; gamma must be finite.
  • The returned host struct can be passed directly to coneprog.

Example

Create a unit-disk cone

soc = secondordercone(eye(2), [0; 0], [0; 0], 1)

Expected output:

soc =
  struct with fields: A, b, d, gamma, Type

Using secondordercone with coding agents

Open a RunMat example with live inputs, then ask the agent to explain how secondordercone changes the result.

Run a small secondordercone example, explain the result, then change one input and compare the output.

FAQ

Can I pass multiple cones to coneprog?

Yes. Pass a cell array containing multiple secondordercone descriptors.
