Would you be so kind to clarify the following Matlab code:
I= (thresh-r)<0;
IU=[~1;I(1:end-1) & ~I(2:end)];
?
where
thresh is the predetermined constant;
I don't understand what does the following line mean:
IU=[~1;I(1:end-1) & ~I(2:end)];

It's ANDing a binary signal with the same binary signal shifted one over. In essence, it appears to produce a "true" where there are two or more values of "r" in a row that are above the threshold.
