Mathematica 7 does not know that Sin[2z] = 2 Sin[z] Cos[z]
It calculates Integrate[1/(Sin[2 z]/2)^193, z] but returns Integrate[1/(Sin[z] Cos[z])^193, z] unevaluated.

reassigning values of elements in matrix
Thanks for the reply. Yes, the second output of unique is already what I want. I actually had a more general re-assignment problem to deal with, in which not just re-assign to the order stats. But now I find out I can just use table lookup or interp1. Say if I want to convert 3 1 4 to 1 2 3, and need to apply thi... 16 Jul 2010 15:27

Count occurences by row
Say I have a matrix a = [ 1 2 2 2 3 3 1 4 5 ]; I want to count the occurences of 1 2 ... 5, but by how many rows. That is, although 2 appears 3 times, but only in 2 rows. I can count the total times by tabulate(a(:)) or histc, accumarray, etc. But to count the total rows, I am doing a for loop for i =... 16 Jul 2010 17:40
