function val = vprob(ev,he)% PURPOSE: returns val = (1/sqrt(2*pi*he))*exp(-0.5*ev*ev/he)% -----------------------------------------------------------% USAGE: val = vprob(ev,he)% where ev = scalar (mean)%       he = scale  (variance)% -----------------------------------------------------------% RETURNS: val = (1/sqrt(2*pi*he))*exp(-0.5*ev*ev/he)val = (1/sqrt(2*pi*he))*exp(-0.5*ev*ev/he);
