I have a 3x15000 matrix and I want to save the segments during a change from NaN to a number. So I have large sections that all 3 rows are NaN and when it changes I want to generate a new matrix. Is it best to index the start and end point? How do I set a flag in order to step through all the data?

if you ONLY get nans in entire columns, this'll work:
numbers = oldmatrix(~isnan(oldmatrix));
numbers = reshape(numbers, 3, []);
