setting up lsqlin constraints

I am trying to solve the equation y=m*x+c, with the constraints c>=A and m>=(c-A)*B.

I would also like to apply weights to y.

I have looked at using lsqlin but am unsure of how to setup the constraints.

Many thanks

lb=[-inf,A];
Aineq=[-1,+B]; bineq=A*B;

w=sqrt(weights(:));

mc=lsqlin(w.*x(:).^[1,0], w.*y, Aineq,Bineq,[],[],lb);

m=mc(1);
c=mc(2);
