function y=nefevmf(x,params,type)   
%NEFEVMF	Evaluate membership function.   
%  
%	Y=NEFEVMF(X, PARAMS, TYPE)   
%	X is the input vector, PARAMS is the parameters   
%	vector, and TYPE is either a string or a number   
%	representing the type of membership function being   
%	used ('trapmf', 'trimf' or 'gaussmf')   
%   
%	For example:   
%   
%		x = (0:0.2:10)';   
%		y1 = evalmf(x, [-1 2 3 4], 'pimf');   
%		y2 = evalmf(x, [3 4 5 7], 'trapmf');   
%		y3 = evalmf(x, [5 7 8], 'trimf');   
%		plot(x, [y1 y2 y3 y4])   
%		title('evalmf')   
%   
%	See also GAUSSMF, TRAPMF, TRIMF.
