shell environment for spawned commands 1604 0
Started by Deleted User
I've written some IDL code that carries out some analysis interactively. What I'd like to do is then use that information as input to some compiled C code routines which I run via a 'spawn' command within IDL. The problem is that the routines require a set of environment variables to be set in order to run. I do that (outside of IDL) by source'ing a shell script. However, it seems that IDL doesn't retain those environment variables. Is there any way to make sure IDL retains those variables --...

Started by Deleted User
Can i create a complex sparse matrix using 'SPRSIN' function
This function, in the oline help, was described :
input argument : An n by n array of any type except string or complex.
But the result (such as : )
>Result = SPRSIN(complex_array)
Result.sa is NOT complex formation only the real part of input complex array with Result.aij is exact.
Have any way to overcome this question

Use of TV function - IDL Virtual Machine 1862 0
Started by Deleted User
Hi all,
I'm getting a problem in displaying a map (INTARR) through TV function, after loading a color table (39)
It works correctly when a call the function in a batch script, but in the VM the same call produce a black and white display (!!). Seems to be really related to the TV function, as other routines (like PLOT) handles colors correctly
Thanks,
Marco

Histogram Error in Itools!! 1591 0
Started by Deleted User
pro testing
num = 10000L
test = randomu(seed,num)
ab = 1.
angle = -Asin(1.-2.*test)/ab
check = 0L
iplot, angle
end
This program simply makes random number between -1.5 Histogram
Checking this histogram, you can see there are some amount of data <-1.5 and also are not data in the region 1.4xx< <1.5.
That is, this histogram is shifted!!!!
This kinds of error is shown in all itools!!

DEM in orthorectification 1597 0
Started by Deleted User
Hi
I am using ENVI 4.1 to orthorectify some aerial photos I have.
The process seems to be working fine except that I have areas on black on the finished product.
I think that this is a problem with the DEM I am using where there are areas of No-Data possibly, causing this omission of the photo.
The DEM I am using is a geotiff which has been converted from an asc file. But I don’t think it is in the best format. (Or data was not converted properly)
I have the original ASC file, ca...

HDF_SD_START: Unable to start the HDF-SD interface. 3245 0
Started by Deleted User
Good day,
I am having problems reading HDF files. The files contain TRMM satellite data from the GSFC DAAC and were downloaded in July 2004. I could not find documentation on whether the files were HDF4 or HDF5 format.
IDL version 6.1.1
OS: Linux (RedHat)
Release: 2.6.10-1.12_FC2
I found reference to similar errors but no solution. Does anyone here know what may the cause of the error and a solution I know that HDF libraries are present but do not seem to be able to read the file...
