FINDARRAY Find one array within another
I = FINDARRAY(A,B,'first') for the array B returns an index array of
the same size as B containing the smallest absolute index in A for each
element of B which is a member of A and 0 if there is no such index.
FINDARRAY(A,B) is the same as FINDARRAY(A,B,'first').
I = FINDARRAY(A,B,'last') for the array B returns an index array of
the same size as B containing the highest absolute index in A for each
element of B which is a member of A and 0 if there is no such index.
I = FINDARRAY(A,B,'all') returns a NDIMS(B)+1 dimensional array such
that I(:,...,k) contains the k-th absolute index in A for each element
of B, 0 otherwise.
