function to find coodinates in an array
Dear list,
I am looking for a function/way to get the array coordinates of given
elements in an array. What I mean is the following:
- Let X be a 3D array
- I find the ordering of the elements of X by ord <- order(X) (this
returns me a vector)
- I now want to find the x,y,z coordinates of each element of ord
Can anyone help me?
Thanks!
