Where Function with Arrays [message #40141]

Hi,
I have two arrays. Both of them have 3 columns (First array:(INDEX, X,
Altitude) and the other array:(INDEX, Y, Altitude). The first column
is the INDEX that I have created to make some intersection with both
arrays.
After the intersection a new array was created to contain all the
intersection points.
Now that I have these values I want to find the respective rows for
each array.
I was trying to do something like that:

int = setIntersection(ArrayX, ArrayY)
newArray = where(XArray[0,*] EQ int[*])

But it is not possible.

With the FOR loop I can do it, but it takes a long time ...

FOR ind = 0L, n_elements(int)-1 DO BEGIN
ValueX = [WHERE(XArray[0,*] EQ int[ind])]
ENDFOR

Is it possible to do without the for loop?

Thank you very much,
Rafael
