Hi,
I got an error sometimes in one of my routines only on AIX.
-- IDL> help,!version,/str
** Structure !VERSION, 7 tags, length=44:
ARCH STRING 'ibmr2'
OS STRING 'AIX'
OS_FAMILY STRING 'unix'
RELEASE STRING '5.4.1'
BUILD_DATE STRING 'Jan 16 2001'
MEMORY_BITS INT 32
FILE_OFFSET_BITS
INT = 32
The same routine works on linux and windows.
The error text is:
% Array has a corrupted descriptor: VAR
the calling sequence is something like this
var=function(x)
First I like to know what's this error is meaning.
It seems to me that's the RETURN statement won't work.
The result value of my function is good.
If it reachs the calling level of the function I got
this error.
Any ideas are welcome.
regards

Hi , peter
I have fixed the problem this morning , just as you said , I took a
mistake about the data type.
Thanks for your reply. Because I am really new to use IDL , and I am
not very familiar about that ,
I think I need to work hard.

Aside from the index-calc issue pointed out in the other post...
You make a single-precision complex array (2 * 4 bytes per element) on the
IDL side but you handle it as a double-precision one (2 * 8 bytes per
element) on the C side. Your C code is going past the end of this array,
tramping over things it shouldn't.
In your C code, use IDL_COMPLEX instead of IDL_DCOMPLEX.
Cheers

^^^^^^
Try i*nr+j
