how do I make a movie out of a timeseries of 2D data?
Hi all, I have an array of 10000 x 200 x 200 numbers... which is a time-series of 200x200 2D data... The 1st dimension is the time index. Is there a way to make a movie out of these data - i.e. playback 10000 frames(200x200) at a playback rate per second? Thanks a lot! [[alternative HTML version deleted]]
