%% Interpolation Without Specifying Points % Copyright 2015 The MathWorks, Inc. %% % Define a set of function values. v = [0 1.41 2 1.41 0 -1.41 -2 -1.41 0]; %% % Define a set of query points that fall between the default points, |1:9|. % In this case, the default points are |1:9| because |v| contains |9| values. xq = 1.5:8.5; %% % Evaluate |v| at |xq|. vq = interp1(v,xq); %% % Plot the result. figure plot((1:9),v,'o',xq,vq,'*'); legend('v','vq');
