I am having a problem in my college project because although the matrix dados_voo is defined (184x4) the programme is giving me the index exceeds matrix dimensions in the variable Longitude. I don't know why this happens to Longitude and not to Latitude that comes before it. Would You kindly help me?
function [velrelsolo0,velrelsolof,Altmax,velvertmax,velvertmin,Distdirect]...
= OpcaoB(dados_voo)
if isempty(dados_voo) == 1
clc
disp('Deverá efectuar a opção A para prosseguir')
MyFlights
else
clc
%Variaveis
Latitude=dados_voo(:,1);
Longitude=dados_voo(:,2);
Altura=dados_voo(:,3);
Tempo=dados_voo(:,4);

Enter this at the command line
dbstop if error
Then run your code. When the error is encountered, the program will pause at the offending line of code with all current workspace variables intact. Then do this:
size(dados_voo)
and start your debugging ...

Thank you, I know where the problem is now. It's loading dados_voo as a structure(1x1) an not as a matrix(184x4)

Your code works as is for me. I ran this:
% Generate random 184x4 vector of data
dados_voo = randi(800, 184, 4);
if isempty(dados_voo) == 1
clc
disp('Deverá efectuar a opção A para prosseguir')
MyFlights
else
clc
%Variaveis
Latitude=dados_voo(:,1);
Longitude=dados_voo(:,2);
Altura=dados_voo(:,3);
Tempo=dados_voo(:,4);
end
Since I received no errors, and you pasted code from a function, my guess is you aren't passing the dados_voo argument/variable correctly.
Without seeing how you are calling your function, it's hard to say.
Hope this helps - good luck!
