function y=umaxbert(u);%UMAXBERT Determination of the maximum value of u for Bertrand distribution.%	Y=UMAXBERT(u) is the function Y(u)=(H(u)+u/2)/(H(u)-u/2)-fmax/fmin. %	Doing UMAX = fzero('umaxbert',0); gives the maximum value for U in the%	computation of the Bertrand distribution. For this distribution, %	 	 H(u) = (u/2)*coth(u/2).%%	U     : real vector%	Y     : value of the function (H(u)+u/2)/(H(u)-u/2)-fmax/fmin.%	P. Goncalves, October 95 - O.
