% BNB18 Finds the constrained minimum of a function of several possibly integer variables.
% Usage: [errmsg,Z,X,t,c,fail] =
% BNB18(fun,x0,xstatus,xlb,xub,A,B,Aeq,Beq,nonlcon,settings,options1,options2,maxSQPiter,P1,P2,...)

% BNB solves problems of the form:
% Minimize F(x) subject to: xlb = x0 =xub
% A*x = B Aeq*x=Beq
% C(x)=0 Ceq(x)=0
% x(i) is continuous for xstatus(i)=0
% x(i) integer for xstatus(i)= 1
