Hi,
I am sure I have seen this ? before, but I can not find it after
searching the resources. I apologize for repeating the ? again, but how
do we multiply a 2D array by a vector?
In more detail, if I have A=FLTARR(5, 3) and B=FLTARR(3), then how do I
multiply each of 5 columns in A by B without a loop?
Thank you,
Pavel

Thanks Marc. Before I wrote the question, I read Help on REBIN but it
did not ring a bell. It is sad to realize how dumb you can be on an
afternoon before a day you plan to take off :-( I am glad today I
haven't written much code that day.
Cheers,
Pavel
