i have 1 3625 x 1 matrix. i have used the following code to flip values based on an index. It gives me a matrix of 1185x1. (as expected)
next =1;
% figure out origin and flip the x and y axis accordingly
for i=1: length(pts)
x_values = flip(x(next:pts(i))) % this finds the walks that start at the other side of origin
this gives me the output i expect.
now where i am having trouble is with replacing the values in my previous matrix with these new values....
pts is 1250, 2434, 3624.
the new matrix x_values is from pts 1250 - 2434.

pts is [ 1250, 2435, 3624] this is the change in time (indicating a new test)
i know it is over-ridding. i dont want it to... i want the expected output to look like this.

Since you have not attached any speciific data, I am generating random values and indices to change.
Hope this helps.

hi thank you for this! much appreciated. the problem is with this code i am writing it to apply to any file i get. the position of index relies on pts which in this particular case is calculated using find change pts. pts is [1250, 2435, 3624]. i also want to stay using text files.....
