any_in

any_in(left,x,right, mask, xx, a,aa, b,bb, c,cc
return the number of elements of the array X which are in the
interval LEFT < X <= RIGHT. Also return MASK, which has the
shape of X and is 1 where X is in the interval and 0 otherwise,
and XX = X(where(MASK)). Up to three optional arrays A, B, and C
of the same shape as X may be supplied; the arrays AA, BB, and CC
analogous to XX are returned. LEFT or RIGHT may be [] for the
interval to extend to infinity on the corresponding side.
LEFT and/or RIGHT may be arrays as long as they are conformable
with X.
