function y=probor(x) %PROBOR Probabilistic OR. % Y = PROBOR(X) returns the probabilistic OR (also known % as the algebraic sum) of the columns of X. If X has two % rows such that X = [A; B], then Y = A + B - AB. If X has % only one row, then Y = X. % % For example: % % x = (0:0.1:10); % figure('Name','Probabilistic OR','NumberTitle','off'); % y1 = gaussmf(x, [0.5 4]); % y2 = gaussmf(x, [2 7]); % yy = probor([y1; y2]); % plot(x,[y1; y2; yy]) % Ned Gulley, 9-19-94 % Copyright 1994-2002 The MathWorks, Inc. % $Revision: 1.14 $ $Date: 2002/04/14 22:21:46 $ if size(x,1)<=1, y=x; return end y=x; for count=2:size(x,1), y(count,:)=y(count-1,:)+y(count,:)-prod(y(([-1 0]+count),:)); end y=y(size(y,1),:);
