Pass control parameters to csdp solver.

Description

Utility function to pass control parameters to csdp solver.

Usage

csdp.control(axtol = 1e-08, 
  atytol = 1e-08, 
  objtol = 1e-08, 
  pinftol = 1e+08, 
  dinftol = 1e+08, 
  maxiter = 100, 
  minstepfrac = 0.9, 
  maxstepfrac = 0.97, 
  minstepp = 1e-08, 
  minstepd = 1e-08, 
  usexzgap = 1, 
  tweakgap = 0, 
  affine = 0, 
  printlevel = 1, 
  perturbobj = 1, 
  fastmode = 0)

Arguments

`axtol`	Tolerance for primal feasibility.
`atytol`	Tolerance for dual feasibility.
`objtol`	Tolerance for relative duality gap.
`pinftol`	Tolerance for primal infeasibility.
`dinftol`	Tolerance for dual infeasibility.
`maxiter`	Maximum number of iterations used.
`minstepfrac`	Minimum distance to edge of feasibility region for step.
`maxstepfrac`	Maximum distance to edge of feasibility region for step.
`minstepp`	Failure is declared if primal line search step size is shorter than this parameter.
`minstepd`	Failure is declared if dual line search step size is shorter that this parameter.
`usexzgap`	If 0, then use objective function duality gap.
`tweakgap`	If 1 (and `usexzgap`=0) then "fix" negative duality gaps.
`affine`	If 1, only use affine primal-dual steps and do not use barrier function.
`printlevel`	If 0, no printing, 1 normal printing, higher values result in more debug printing.
`perturbobj`	Amount of objective permutation used.
`fastmode`	If 1, csdp will be faster but also less accurate.
