function dtwplot2(vec1, vec2, dtwPath) 
% dtwPlot2: Plot the result of DTW of two pitch/MFCC vectors
%	Usage: dtwplot2(vec1, vec2, DTWpath)
%
%	For example:
%		vec1=[71 73 75 80 80 80 78 76 75 73 71 71 71 73 75 76 76 68 76 76 75 73 71 70 70 69 68 68 72 74 78 79 80 80 78];
%		vec2=[69 69 73 75 79 80 79 78 76 73 72 71 70 70 69 69 69 71 73 75 76 76 76 76 76 75 73 71 70 70 71 73 75 80 80 80 78];
%		[minDist1, dtwPath1, dtwTable1] = dtw1(vec1, vec2);
%		[minDist2, dtwPath2, dtwTable2] = dtw2(vec1, vec2);
%		subplot(2,1,1); dtwplot2(vec1, vec2, dtwPath1); title('DTW alignment by dtw1');
%		subplot(2,1,2); dtwplot2(vec1, vec2, dtwPath2); title('DTW alignment by dtw2');
