Hello, all: I need some suggestions on the scaling of list: I have a set of 2 level list A: -0.07839 0.027997 -0.07962 0.009307 0.116985 0.971994 0.898549 1.038538 -0.04786 0.012652 -0.07927 0.009344 0.086011 0.981513 0.858625 1.0432 -0.02895 0.006401 -0.07636 0.009381 0.067194 0.986076 0.819673 1.047881 -0.01743 0.003326 -0.07294 0.009418 0.055841 0.988423 0.782341 1.052581 -0.01074 0.01575 -0.06966 0.005007 0.049008 0.995316 0.746731 0.528657 -0.00641 0.000256 -0.06627 0.00503 0.044812 0.995626 0.712755 0.531166 -0.00382 2.89E-06 -0.06304 0.005052 0.04231 0.995686 0.680436 0.533686 -0.00227 -0.00016 -0.05996 0.005075 0.04082 0.995643 0.649692 0.536218 -0.00135 -0.00027 -0.05704 0.005097 0.039933 0.995534 0.620447 0.538761 -0.0008 -0.00035 -0.05426 0.00512 0.039406 0.995378 0.592629 0.541315 each sublist has 8 elements. Now I need to find the maxima and minima for each column ( as above). I use the following code: minlist=Apply[Min, Transpose[A],1]; maxlist=Apply[Max,Transpose[A],2]; Now I want to use x'=(x-xmin)/(max-min) for each entry in the above matrix How can I implement it in a list or matrix? Thanks Sabrina
