Piecewise linear quadratic (plq), function effective domain
I = plq_minPt(plqf)
matrix. A PLQ function.
1x2 matrix [lb;ub]. Gives the interval [lb,ub] on which plqf is finite.
Computes and returns the effective domain of the given PLQ function. Assumes that the effective domain of the function is connected, so that the effective domain is either a closed interval [lb,ub], or the empty set (if plqf is %inf everywhere).
This function runs in O(1) time.
