search for: 10400000th

Hi, I'm hoping someone can offer some advice:I have a matrix "x" of dimensions 160 by 10000. I need to create a matrix "y", where the first 7 elements are equal to x[1]^1/7, then the next 6 equal to x[2]^1/6, next seven x[3]^1/7 and so on all the way to the 10400000th element. I have implemented this with a for loop an hour ago and it is still loading, can anyone offer any suggestions as to how I can create this matrix without using loops? I would really appreciate any suggestions. Regards, Andre [[alternative HTML version deleted]]
