This probably sounds like a stupid question but does anybody know of an IDL
equivilent to the CONTINUE command in C/C++ ? Your help would be much
appreciated.

Just wondering if this is not fast enough?

a= INDGEN(6)
PRINT, a#REPLICATE(1,4)

and
PRINT, REPLICATE(1,4)#a

(I am still reading David's page on rebin_magic).

I think you better have a look at the Dimensional Juggling Tutorial:

http://www.dfanning.com/tips/rebin_magic.html

You will be surprised and amazed by what you find there.
Most people who read it can speed their IDL code up by a
factor of a 100 at least!

Cheers,

David

IDL Analyst provides extra mathematical and statistical routines (from
the IMSL C Numerical Library), so it's an add-on to IDL.

IDL> result = reform(transpose([[array1], [array2]]), 6)

Or, in the case where the values in the arrays are not necessarily in
increasing order:

IDL> array1=['aA', 'aC', 'aE']
IDL> array2=['bB', 'bD', 'bF']
IDL> array3=(transpose([[array1],[array2]]))[0:*]
IDL> print,array3
aA bB aC bD aE bF

Well, it's there. You just might not have a license to use it.

Is this true? I don't see anything about Analyst being included in
IDL 6.4 on the RSI web site...
