Hi Matlab Experts,
I've got a basic question.
If I've created a matrix:
data_bounds = [event_samples(1),event_samples(end)]; % let's say its value is [79502,5316744]
In my case, this data_bounds variable corresponds to column numbers in another matrix (say it is called "data"). How do I pull the columns from data between the values of data_bounds?
Thanks!

desiredData = data(:,event_samples(1):event_samples(end))

Hi,
I tried that, but I get the error
"Index in position 2 exceeds array bounds (must not exceed 5272240)".
Do you have any ideas why this may be?
Thanks!

That means the "data" variable does not have 5272240 elements in it, which means you are calculating the bounds wrong.
Or you actually store data as row, in which case you should use
desiredData = data(event_samples(1):event_samples(end),:)
What is the size of your data variable?
