Hello everyone. i am going to try give you as much information as possible. i know it may seem like a simple question but i am ripping my hair out.
ok so my original txt file has over 3000 rows of data and 5 columns.i have written a code that goes through the time (column 2) and identifies a change. That change in time corresponds to the start of a new test. For the original text file i found i have 3 tests, hence, 3 .mat files that i have saved using the following script. Each .mat file has 3 columns and multiple rows and each .mat file corresponds to a seperate test (like i mentioned). the columns are x,y, test condition 1 -18 etc.
pts = findchangepts(data(:,2), 'Statistic', 'linear', 'MinThreshold',100)
pts(end+1) = finalrow;
num_step = data(:,1)
x = data(:,4);
y = data(:,5);
fin = 1;
next = 1;
matrix = [x(next:pts(i,:)), y(next:pts(i,:)), test_cond(next:pts(i,:))];
filename = sprintf('%s_%d','test',i);
next = pts(i);
if pts(i) == length(pts)
fin = 0;
NOW i want to write code to do whatever it is i want it to do and i want it to do it to each mat file.
i.e. go through each test and find all the zeroes, save those in a seperate file blah blah blah.
i know i have to use a loop but some advice as to the best and most efficent way to execute this would be great.
my coding is not fantastic so please, if you dont have anything useful or nice to contribute dont do it at all. thanks.
