; MESHDOM,x,y,XR,YR
;
; MESHDOM calculates arrays XR and YR that index a region with
; value pairs from (x,y). The arrays are of size Nx columns by
; Ny rows, where Nx is the length of x and Ny is the length of y.
; Each row of XR equals the vector x, and each column of YR
; equals the vector y.
;
; USAGE
; x=indgen(10) + 5
; y=indgen(5) - 3
