Handling multiple closing peaks: displaying a command to change the method

[MinhChauNGUYEN]

Like the opening peaks, the closing peak can be imprecise and there are various different types which shouldn't be treated by the same method. Therefore, in the part that peakdet asks for user's verification of f0 (besides resetting the threshold, or suppressing the initial or final cycles), the choice of selecting other method to handle multiple peaks shoud be offered here.
User can type >>0 for 'selecting the highest among the peaks'; >>1 for 'selecting the first peak', etc.
The f0 and oq values after that will be re-caculated according to the new method which is more suitable.

Good idea.

An overhaul is under way. This request has been integrated to the project for version 1.1. The various possibilities for f0 will be proposed first, and Oq calculated later.

This is a preview. Colour codes are just a first try.

Another example, using the 1st token in the gallery:

% Method 1 (max DECPA): green.
plot(f0(:,1), 'LineStyle','-', 'LineWidth', 1.5, 'Marker', 'o','Color', [.0863 .7216 .3059], 'MarkerSize',10, 'MarkerFaceColor', [.0863 .7216 .3059])

% Method 2 (first peak): red.
plot(f0(:,2), 'LineStyle','-', 'LineWidth', 0.5, 'Marker', 'o','Color', 'red', 'MarkerSize',2, 'MarkerFaceColor', 'red')

% Method 3 (last peak): black.
plot(f0(:,3), 'LineStyle','-', 'LineWidth', 0.5, 'Marker', 'p','Color', 'black', 'MarkerSize',2, 'MarkerFaceColor', 'black')

% Method 4 (barycentre): blue diamonds.
plot(f0(:,4),'db','MarkerSize',13)

% Method 5 (most salient pulse on 2nd derivative): orange.
plot(f0(:,5), 'LineStyle','--', 'Marker', 's','Color', [1 .7961 .3765], 'MarkerSize',9)

% Method 6: excluding double peaks
plot(f0(:,6), 'dg','MarkerSize',8)

The f0 matrix now has six columns instead of just one.
