Hello. I’d like to know the way to enter the name of the song chords into the structure of MATLAB easily.
I do research about the related between chords and a piece of music, and I analyze the chords progression in MATLAB. Howerver, it takes too many time to enter the name of chords by hands like this;
chords = struct( …
‘name’, {}, … % name of chords（ex: ‘Cmaj7’）
‘start_sec’, {}, … % start time[s]
‘end_sec’, {} … % end time[s]
);
N=input(‘the number of chords: ‘);
BPM=input(‘BPM: ‘);
chords(1).start_sec=0;
for i=1:N
fprintf(‘n===== Chord %d =====n’, i);
chords(i).name=input(‘Name: ‘); %”
Start=input(‘Start beat: ‘);
chords(i).start_sec=(60/BPM)*4*(Start-1);
if i >= 2
chords(i-1).end_sec=(60/BPM)*4*(Start-1);
end
end
ends=input(‘End beat: ‘);
chords(N).end_sec=(60/BPM)*4*ends;
save("chords_yoruni.mat","chords");

I am a beginner when it comes to programming, so I don’t have any idea. I would like you to tell me even small things.
