I have a hyspectral image, with 62 bands, b1, b2,..., b62, in ENVI
format and I want to import that image into IDL. I have a vector with
62 elements, k1,k2,...,k62, that matches with the bands. I'm going to
use the equation y1=b1/k1, y2=b2/k2,...,y62=b62/k62 and then export it
as an image with the same number of bands but new values. I think I
need to use ENVI_GET_DATA but it imports individual bands, I wonder
how I can use a loop to import the whole bands and then another loop
to do the math operations?
