index exceeds the number of array elements (5)

I have a basic Matlab script that has been working fine for weeks and now it throws an error

'Index exceeds the number of array elements (5)."

Error in test (line 27)

subplot(4,2,2),plot(testTime,emg2),ylim([-128 128]);title('emg2');

How do i know what index in what array the error is talking about?

It still plots the 1st graph but nothing after that, when i quit matlab and run it works fine but wont run again unless i quit out of matlab

CAn anybody suggest what i can do to debug this script?

testData = m1.emg_log;
testTime = m1.timeEMG_log;

completeDataSet = [testTime,testData];
emg1=testData(:,1);
emg2=testData(:,2);
emg3=testData(:,3);
emg4=testData(:,4);
emg5=testData(:,5);
emg6=testData(:,6);
emg7=testData(:,7);
emg8=testData(:,8);

figure;
subplot(4,2,1),plot(testTime,emg1),ylim([-128 128]);title('emg1');
subplot(4,2,2),plot(testTime,emg2),ylim([-128 128]);title('emg2');
subplot(4,2,3),plot(testTime,emg3),ylim([-128 128]);title('emg3');
subplot(4,2,4),plot(testTime,emg4),ylim([-128 128]);title('emg4');
subplot(4,2,5),plot(testTime,emg5),ylim([-128 128]);title('emg5');
subplot(4,2,6),plot(testTime,emg6),ylim([-128 128]);title('emg6');
subplot(4,2,7),plot(testTime,emg7),ylim([-128 128]);title('emg7');
subplot(4,2,8),plot(testTime,emg8),ylim([-128 128]);title('emg8');

I am pretty new to Matlab so not 100% familiar with it yet

What does

which plot

show?

It sounds like you have a variable called plot (or possibly one called ylim or subplot, but that is probably less likely)

[Walter Roberson]

my guess is that it was title that is used as a variable .

[Adam]

That does seem to match the error that get if I test it out, though interestingly I also get the helpful message underneath the error, that I have never seen before and that I don't get if I overwrite the plot function with a variable:

Thanks for the responses

I have got a bit closer to figuring out the problem, i have another script that i call at the end that i use to save the recorded data to an excel spreadsheet and something is causing the error in that script

Solved this issue

the other script i was linking to had a variable called title which was confusing the program
