ECOS_update: Update numerical data in an ECOS workspace

In ECOSolveR: Embedded Conic Solver in R

Update numerical data in an ECOS workspace

Description

Replaces numerical values in an existing ECOS workspace without repeating symbolic analysis. The sparsity structure must remain the same; only the non-zero values of G and A, and the dense vectors c, h, b can be updated. Pass NULL for any argument to leave it unchanged.

Usage

ECOS_update(workspace, Gpr = NULL, Apr = NULL, c = NULL, h = NULL, b = NULL)

Arguments

workspace	an external pointer of class "ecos_workspace" as returned by ECOS_setup.
Gpr	numeric vector of new non-zero values for G (same length as original), or NULL to keep current values.
Apr	numeric vector of new non-zero values for A (same length as original), or NULL to keep current values.
c	numeric vector of new objective coefficients, or NULL.
h	numeric vector of new inequality RHS, or NULL.
b	numeric vector of new equality RHS, or NULL.

Value

the workspace object, invisibly.
