%% Uncertain Real Parameter with Nonsymmetric Range % Create a nonsymmetric parameter. The end points are % 1 normalized unit from nominal, and the nominal is 0 normalized units % from nominal. Moreover, points inside the range are less than 1 unit from % nominal, and points outside the range are greater than 1 unit from % nominal. However, the relationship between the normalized distance and % numerical difference is nonlinear. % Copyright 2015 The MathWorks, Inc. au = ureal('ua',4,'range',[1 5]); NV = actual2normalized(au,[1 4 5]) %% NV = actual2normalized(au,[2 4.5]) %% NV = actual2normalized(au,[0 6]) %% % Graph the relationship between actual and normalized values. The % relationship is very nonlinear. AV = linspace(-5,6,250); NV = actual2normalized(au,AV); plot(NV,AV,0,au.NominalValue,'ro',-1,au.Range(1),'bo',1,au.Range(2),'bo') grid, xlabel('Normalized Values'), ylabel('Actual Values') %% % The red circle shows the nominal value (normalized value = 0). The blue % circles show the values at the edges of the uncertainty range (normalized % values = -1, 1).
