IM_GRAY

Fixed mapping converting multi-band images to gray images

   B = IM_GRAY(A,V)
   B = A*IM_GRAY([],V)
   B = A*IM_GRAY(V)

Input
A	Multiband image or dataset with multi-band images as objects
V	Weight vector, one weight per band. Default: equal weights.  (weights will be normalized to sum to one)

Output
B	Output image or dataset.

Description

The multi-band components in the image A (3rd dimension) or in the  objects in the dataset A are weigthed (default: equal weights) and  averaged.
