I have 4 very large arrays, a, b, c, and d of the same size. I have selected specific elements in 'a', and I need the corresponding elements from b, c, and d (i.e. if I select an element from 'a' want the elements from the other arrays that have the same index).
However, I only know the the elements that I am interested in, not their indices because they were analytically selected.
I am trying to go into the array find the element I am interested in, then some I need to be able to retrieve the index of that element.
data = pl.loadtxt('mydata1.cat') i = np.array(5448) a = data[:,3] b = data[:,9] c = data[:,10] d = data[:,11] j = 34.44 for h in a[i]: if h == j: print a[i] , b[i], c[i], d[i] else: print "no!"
