J = VL_IMARRAYSC(A) behaves as VL_IMARRAY(A), but scales the range of each image to span the current colormap.
VL_IMARRAYSC(...) displays the composed image rather than returing it.
VL_IMARRAYSC() works only with indexed (or gray-scale) images.
VL_IMARRAYSC() accepts the options of VL_IMARRAY() and:
Specify the intensity range. If empty, the range is calcualted automatically for each image in the array.
If true all the images in the array are scaled in the same range.
