% - field?: string : field name

%
|
|
% <OUTPUT>
|
|
% - OPTION: structure data: each field is as follows:
|
|
% * maxIteration : The maximum number of iterations.
|
|
% * epsilonStar : The accuracy of an approximate optimal solution
|
|
% for primal and dual SDP.
|
|
% * lambdaStar : An initial point.
|
|
% * omegaStar : The search region for an optimal solution.
|
|
% * lowerBound : Lower bound of the minimum objective value of
|
|
% the primal SDP.
|
|
% * upperBound : Upper bound of the maximum objective value of
|
|
% the dual SDP
|
|
% * betaStar : The parameter for controlling the search direction
|
|
% if the current point is feasible.
|
|
% * betaBar : The parameter for controlling the search direction
|
|
% if the current point is infeasible.
|
|
% * gammaStar : A reduction factor for the primal and dual step
|
|
% lengths.
|
|
% * epsilonDash : The relative accuracy of an approximate optimal
|
|
% solution between primal and dual SDP.
|
|
% * isSymmetric : The flag for the checking the symmetricity of input
|
|
% matrices. (0 => no check, 1=> check)
|
|
% * isDimacs : The flag to compute DIMACS ERROR
|
|
% (0 => no computation, 1=> computation)
|
|
% * xPrint : (default %+8.3e, NOPRINT skips printout)
|
|
% * XPrint : (default %+8.3e, NOPRINT skips printout)
|
|
% * YPrint : (default %+8.3e, NOPRINT skips printout)
|
|
% * infPrint : (default %+10.16e, NOPRINT skips printout)
|
|
% * print : Destination of file output. the default setting is
|
|
% stdout by 'display'.
|
|
% If print is set 'no' or empty, no message
|
|
% is print out
|
|
% * resultFile : Destination of detail file output
|
|
% * NumThreads : Number of Threads for internal computation
