Hello,
The attached file has some nan values. I want to separate all non-nan data sections and apply low-pass filtering. Can you help me to select non-nan data sections in this txt file, so I can apply filtering for each non-nan data sections separately.
Thank you

test = load('test.txt');
mask = ~isnan(test.');
starts = strfind([0 mask], [0 1]);
stops = strfind([mask 0], [1 0]);
Now starts(K) is the index of the first non-nan in a group and stops(K) is the index of the last non-nan in the group.
