I have a movie downsampled by a jit.matrix attached to both jit.iter and jit.cellblock, trying to get luminance values. Two things are confusing:
1. jit.iter gives different values upon banging it than the values that appear in jit.cellblock -- why these different values?
2. If I click in jit.cellblock or change it's size with the mouse or even command-click in a different part of the patch when edit mode is on, the jit.cellblock values change, EVEN THOUGH THE MATRIX DATA IS NOT GOING THROUGH THE CONNECTION. Even if I disconnect the matrix from the cellblock, these data values change with every click of the mouse. Only if I stop the metro that runs the jit.qt.movie do these values stop changing.
I have not seen in any documentation why this behavior. Why are the values different coming out of jit.iter than those I see in jit.cellblock? Why do jit.cellblock values constantly change for no apparent reason. And finally, which values do I believe are the correct ones for the matrix values?
