Please help with the Inequality

In the following code:

x = lsqlin(C,d,A,b,Aeq,beq,lb,ub,x0,options)

lb and ub are such that lb<=x<=ub.

Is there a way to change it to

lb < x < ub (strict inequalities)

Thanks

Multiply the values in your lb array by (1+eps) and multiply the values in your ub array by (1-eps)

thanks. could you please explain what "eps" means?

Is it a small number epsilon ?

my lb = [ 0 0 ] and ub = [1 1]

so even if I multiply by (1+eps) i still get the same answer !

Can you please suggest something?

Thanks

You could use realmin as your lower bound. Unless, that is, it is important to be able to accept the denormalized values as well. If you need the denormalized values too, use eps(realmin) as your lower bound.
