AOVERLAY One function for Overlapping/Overlaying 2 arrays, using a row/column coordinate system. Calls AOVERLAP . !!NEW!! MAKEARRAY
Same as AOVERLAP, has only a new optional argument "o", If "o" is 0 or omitted the function does overlapping, if any value<>0, does overlaying, (areas outside base array, after overlapping, are excluded).
Excel Formula:
=LAMBDA(a,b,[r],[c],[o],
    LET(w,ROWS(a),l,COLUMNS(a),x,AOVERLAP(a,b,r,c),
      IF(o,MAKEARRAY(w,l,LAMBDA(m,n,INDEX(x,IF(r>=0,m,m-r),IF(c>=0,n,n-c)))),x)
    )
)
