function [p,d] = check(X)

|
% CHECK(F) Displays/calculates constraint residuals on constraint F
|
|
%
|
|
% [pres,dres] = CHECK(F)
|
|
%
|
|
% pres : Primal constraint residuals
|
|
% dres : Dual constraint residuals
|

|
|
% If no output argument is supplied, tabulated results are displayed
|
|
%
|
|
% Primal constraint residuals are calculated as:
|
|
%
|
|
% Semidefinite constraint F(x)>0 : min(eig(F))
|
|
% Element-wise constraint F(x)>0 : min(min(F))
|
|
% Equality constraint F==0 : -max(max(abs(F)))
|
|
% Second order cone t>||x|| : t-||x||
|
|
% Integrality constraint on x : max(abs(x-round(x)))
|
|
% Sum-of-square constraint : Minus value of largest (absolute value) coefficient
|
|
% in the polynomial p-v'*v
|
|
%
|
|
% Dual constraints are evaluated similarily.
