Hi,

I want to run a for loop (the "for probe = 1:n_trial" in the example below) for a specific number of times (e.g., 7). However, I want it to continue the iteration over a longer vector array (e.g., "longer_array" with 84 values). Every time the loop comes back, it should continue iterating on that vector (for example, the first time it would go from 1 to 7, the second time from 8 to 14, etc.).

I'm not sure if I'm explaining myself correctly. Anyway, here an example of the code:

n_trial = 12;
n_probe =7;
longer_array = [1:84];
for trial = 1:n_trial
    for probe = 1:n_probe
    %do something here
    end
    %do something here
end

Any help with this would be very much appreciated.

Thanks,

Mikel

在 MATLAB Online 中打开

n_trial = 12;
n_probe =7;
longer_array = [1:84];
for trial = 1:n_trial
    for probe = 1:n_probe
       longer_array((trial-1)*n_probe+probe);%index into your longer_array
    end
    %not sure what you want to do here, explain
end
