function [c, A] = ctp6(x, ctrl)
%Call: [c A]=ctp6(x,ctrl)
%Evaluate both the constraints and the corresponding
%Jacobian if ctrl>0, for the problem below at x
%The problem is defined as c(x)>=0
%and x(i)>=0 for all i.
%
if ctrl == 0
    c(1)=x(1)^2+x(2)^2+x(3)^2-25;
    c(2)=8*x(1)+14*x(2)+7*x(3)-56;
    c=c(:);
    A=[];
else
    c=[];
    A=[];% indicate Jacobian should be difference computed
