calculation of negentropy
If what you say is true &#8220;that this result is off because of general statistics&#8221; then limit of negE when the number of samples go to infinity should go to zero. This is not the case, since it explodes, so there should be something wrong with the normalization. I = randn(10000000,1); p = hist(I,1000000)... 19 Nov 2009 07:13

Apart from the "usual" loop method, does matlab know a better way of finding the position of a maximum value in x(1:100) array ? Say I have, an array with 100 values inside. The maximum is at the position 53. How to get that position in a variable ? All ideas appreciated ... With best regards, Luka ... 18 Nov 2009 23:34
