Your question is not very clear, but I am guessing that what you want
is to find out which points have the maximum/minimum x and y values.
Which would be something like:

x_max_val=max(x,x_max_ind,min=x_min_val,subscript_min=x_min_ ind)
y_max_val=max(y,y_max_ind,min=y_min_val,subscript_min=y_min_ ind)

Which would give you the maximum value of x in x_max_val and the index
where that occurs in x_max_ind. That is,
x_max_val==x[x_max_ind]==max(x).
