I generate a logistic sequence from a matrix,the values of this sequence are negative ,how should i compute the max of this sequence?

i need the max of this sequence in order to have a Descending order of sequence indexes, thanks for guiding me.

Hi, if I understand well you need to sort a sequence of real values in descending order ? For example you can use the MATLAB function "sort" or any equivalent function in another language
