Differences between > and GT or < and LW 1400 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 1665 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 1681 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 1916 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
-Thanks

Cascading (Available) License detection 1332 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 1782 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...

Generate a .sav that can not be restored 1788 2
Started by Deleted User
Hi,
I have to deliver an IDL program to a client. The easy way is to generate a .sav file and giving it to him. The problem is that with the RESTORE procedure, my client can see my whole program and then modify it or reuse it. Is there a way of transmitting an IDL program to someone without him being able to use the RESTORE procedure but him being able to use it with the right IDL command
Thanks
