Hello,
I am new to using the ENVI API, but I would like to perform band math using bands from multiple rasters as input. When using the ENVI GUI this is easy to do as I can simply click to assign bands from differing images.
I was thinking of creating a large metaspectral raster and combining bands from different images into one large image, but I don't think it would be efficient for what I am trying to do.
As an example, I have two 6 band images and would like to process each band using the formula:
Bandx_Image1 * (1 /Bandx_Image2)
But I don't know how to assign multiple images.
Hope someone has a hint, or solution!
Thanks.

You could try something like this example. It uses ENVI Classic code but will work:
