function y=umaxdfla(u);%UMAXDFLA Determination of the maximum value of u for D-Flandrin distribution.%	Y=UMAXDFLA(u) is the function Y(u)=(H(u)+u/2)/(H(u)-u/2)-fmax/fmin. %	Doing UMAX = fzero('umaxdfla',0); gives the maximum value for U in the%	computation of the D-Flandrin distribution. For this distribution, %	 	 	H(u) = 1+(u/4)^2.%%	U     : real vector%	Y     : value of the function (H(u)+u/2)/(H(u)-u/2)-FMAX/FMIN.%	P. Goncalves, October 95 - O.
