When I run the sample for speech recognition using dtw at https://www.mathworks.com/help/signal/ref/dtw.html#d120e38502 in the browser version of MatLab it works but shows an error. However, when I run it in MatLab on my computer, the line with "[d,i1,i2] = dtw(a1,a2);" throws a code stopping error saying "Too many output arguments." This is an example from the MatLab documentation so I would figure that it should work especially since it does work in the online version. In order to learn how to use this function properly, I need for the example to work. The full code from the example is shown below. The line that throws the error is shown in BOLD. Can someone help me with this?
load mtlb
a1 = mtlb(round(0.15*Fs):round(0.25*Fs)); a2 = mtlb(round(0.37*Fs):round(0.45*Fs));
subplot(2,1,1) plot((0:numel(a1)-1)/Fs+0.15,a1) title('a_1') subplot(2,1,2) plot((0:numel(a2)-1)/Fs+0.37,a2) title('a_2') xlabel('Time (seconds)')
[d,i1,i2] = dtw(a1,a2);
a1w = a1(i1); a2w = a2(i2);
t = (0:numel(i1)-1)/Fs; duration = t(end) duration = 0.1297 subplot(2,1,1) plot(t,a1w) title('a_1, Warped') subplot(2,1,2) plot(t,a2w) title('a_2, Warped') xlabel('Time (seconds)')
