Hovmoller Help 1389 0
Started by Deleted User
I am attempting to create Hovmoller diagrams using NetCDF data from satellite images. Has anyone done this before and if so, some pointers would be helpful. My data is as follows (for a sample of two files):
temp=ARRAY&912000,2000,2&93
lon=ARRAY&912000,2000,2&93
lat=ARRAY&912000,2000,2&93
time=ARRAY&912&93
Thanks for your help

IDLDE Crashes once loaded 1349 1
Started by Deleted User
When I run idlde (8.3) with the hot fix under Linux. The DE shows up and then crashes with this error message in the terminal:
Problematic frame:
C &91libpthread.so.00x10eb8&93 __lll_unlock_elision0x18
I am running Arch Linux which tends to run the latest packages and that library is linked to glibc.
IDL works normally otherwise.
Any suggestions

Hello, I'm trying to run a code and it calls in a procedure. the execution is halted , because it says "Attempt to call undefined procedure/function". I just want it to give up, but the "run" button gets replaced by the 'resume' button, and pressing 'stop' doesn't work either (the play button is still replaced by the resume button). I can exit IDL and re-open it, and my Play button is back, but I was hoping someone knew a quicker way.

H5A_* increasing slowness 1932 1
Started by Deleted User
I am creating an object to parse the metadata in HDF5 files in a manner similar to H5_Parse. One difference, though, is that all groups, attributes, datasets, etc. remain open until the object is destroyed. I am parsing many files. If I parse them individually, closing each one before parsing the next, execution time increases linearly with the number of files. If I parse all files at once (closing only after all have been parsed), however, the H5A_* routines taking an increasing amount of time....

Newbie Question 1329 1

Hello,
I am literally just getting started with IDL so forgive me for making any seriously obvious mistakes. I am just running a few batch examples from the ENVI Reference Guide. I've just copied and pasted the CROSS_TRACK_CORRECTION_DOIT example into the IDL DE, save it, compile it, and run it. It seems to compile successfully and run through the couple of print statements I threw in for understanding. But it doesn't create a logfile or an output image. I know this is probably something ex...
