Hi, I was trying to using hilbert function to get the amplitudes and phases of the long-recording signal, but got the error "out of memory" due to the huge dataset. Thus, I'm wondering what's the size limit for this function. And could you give me any suggestions on how to deal with this issue? If I just cut the signal to two parts, the result would be different, right?

Hi Yuechen,
The maximum size limit of the input data to the 'hilbert' function is the maximum array size limit allowed by MATLAB. This limit is obtained by typing 'memory' in the command window. In order to use huge dataset in a single time would be to reduce the double precision data to a single precision data using the 'single' function.
