Hello,
I input my data as three different variables, acc, gyr, and mag. I want a small amount of code that makes all three variables the length of the shortest variable.
For example, if acc is 12000x1 and gyr is 12000x1, but mag is 12001x1, how can i automate deleting this row to make the vectors all the same length.
Thank you for your help,
Adam

One way,
collection = {acc,gyr,mag};
minlen = min(cellfun('length',collection));
clipped=cellfun(@(z)z(1:minlen),collection,'uni',0);
[acc,gyr,mag]=deal(clipped{:})

but note that,
>> isvector(rand(12000,3))
ans =
logical
0

Maybe this:
lastRow = min([length(acc), length(gyr), length(mag)])
% Crop
acc = acc(1 : lastRow);
gyr = gyr(1 : lastRow);
mag = mag(1 : lastRow);
