Hey, so I got a variable of duration that has de time of each message that goes from 00:00:00 to 23:59:59 and I want to make a plot that show me the amount of messages each hour. How could I do it? I made this but I got an error:
Hours_24 = (0:1:23)/24;
figure(1)
plot(Hours_24,Time_AIS1);
The error showed is:
Error using plot
Vectors must be the same length.

Your question suggests that you're trying to count the number of messages per hour but the code you shared suggests the problem is with plotting. So the question is not clear to me.

well I've got Time_AIS1 that has the time of all the messages and I want a figure that shows me 24 columns where each column has the mesages that have the same Hour. In total there should be just 24 columns.

Easy solution might be this, e.g.:
N = numel(Time_AIS1);
figure(1)
stem(1:N, Time_AIS1), xlabel('Hour'), ylabel('# of messages')
