dir

string ("succ" or "pred")

x

real scalar, vector or matrix

This function computes, in the element wise meaning, the corresponding neighbours of the elements of x (in the underlying floating point set, see number_properties), the successors if dir = "succ" and the predecessors if dir = "pred".
