Floating illegal operand with EXP and real numbers 2273 0
Started by Deleted User
I have code running on two separate 64-bit Linux machines. One machine is running IDL v8.2 while the other is running v8.2.2 (these machines are owned by different entities, thus the different versions and licenses).
When I run my code on the v8.2.2 machine, however, I get "floating illegal operand" errors that I do not get on the v8.2 machine. Tracking this down reveals that the errors are created when using the "EXP" function with real numbers (as opposed to NaN values).

Differences between > and GT or < and LW 1617 1
Started by Deleted User
Hi everyone,
I am trying to use the where function and i have found a dilema. My results are differents if i use the > than if i use GT. I had read the IDL online help but i don't understand the difference. I think where I use the > symbol, the values lower than the condition are set equal to the condition and with GT the values lower than the condition are ignored, isn't it
Thank you in advice.

IDL & ENVI License Server Security Patch 1915 0

Harris Geospatial Solutions (Exelis VIS) was recently made aware of a security vulnerability in the Flexera FlexNet Publisher technology that is utilized for license management of the IDL & ENVI software products. This security vulnerability applies to all current and older versions of our software and applies to scenarios where a license server is utilized which includes network floating (FL) type licenses and some node-locked (SN) type licenses that use a license manager.

Change the path where IDL search the variables 1957 1
Started by Deleted User
Hello everyone,
I am starting to work with IDL. My problem is very basic I think, I don't know how to change the path where IDL has to go to search the variables. I have set the workspace and read the .pro files perfectly but when I write, for example: viewspe, '20160308T180138.spe'
OPENR: Error opening file. Unit: 1, File: C:\Users\hp\20160308T180138.spe
The path of the workspace is C:\Users\hp\Desktop\UMASS\FMCW_pruebas\, and is where my variables are.
Someone can help me
Ruben

HISTOGRAM function 2246 2
Started by Deleted User
Here is a example code
mn = 0.8d
mx = 1.5d
step = 0.23d
arr = &91mn:mx:step&93
h = histogram(arr, min=mn, max=mx, binsize=step, loc=loc)
print, h
print, value_locate(loc, arr)
The output of histogram function is wrong.
Correct output is &911, 1, 1, 1&93.
This result is related to this post http://www.idlcoyote.com/math_tips/ra...
Do you have any plane for fix this bug

Cascading (Available) License detection 1591 0
Started by Deleted User
I'm trying to figure out how to configure two license pools. We expect, in general, to have only a couple users of our application (1 - 3) at any given time, for which we intend to purchase a small pool of dedicated licenses. BUT, in the event we get the occasional additional demand, we would like to fail over to a larger pool used by the broader group of which we are a part. This will also allow us to determine if our dedicated pool is too small.
I am aware that IDL looks through a series of...

Get statistics of ROI or Shapefile from a Landsat image 2041 1
Started by Deleted User
Hello,
I am trying to run a linear unmixing (aka spectral mixture analysis) process on several hundred landsat images. The endmembers are taken from the image itself. I wrote a code using an evf vector file that worked well. I am updating the code now that we have a newer version of IDL and can't figure out how to do this. Essentially, I want the mean values for all bands from regions designated on the image as derived from the shapefile or roi (as a polygon or point). I am not sure how to get s...
