Gaussian Distribution with Specified Mean and Sigma 1864 2
Started by Deleted User
Hello,
I have to simulate a sensor response, which has spectral response functions of Gaussian from 380 to 2510 nm with 10 nm sampling and 12 nm FWHM.
sigma = FWHM / 2.35
mean = 0
array = RANDOMN(seed, 60) ; it is 60, assuming 30th band is the center band.
new_distribution = array * sigma mean
However, the generated numbers are not what I expected, ranging from -5 to 5. I was expecting a set of numbers ranging between 0 and 1, center band has the highest value 1, FWHM of the bell curve ...

Hello--
I've recently purchased and set up a hardware random number generator (the TrueRNG2 from ubld.it) which generates random numbers for the entropy pool on a linux machine. The random number functions in IDL (e.g. randomu(seed)) can only generate pseudo-random numbers from IDL's hard-coded algorithm, correct How can I have IDL (i.e. what function should I use to) construct random numbers from the computer's entropy pool or even from pre-existing random number generators built into lin...

Creating variables/structures with a foreach loop 2022 2

Hello,I want to create variable names (that I want to use later in the program) through a foreach loop. I want the variable names: dist100, dist200, dist300 etc. and assign an array to those (e.g. &9199, 99&93). Then I want to use those variables later on to do some further calculations, so I want to be able to e.g. add values to them to make them &9199, 99, 34, 56, 87, 32&93 etc. Is there a simple way doing thisI also tried creating structures this way (see below):distarray = &91100, 200,...

how to access read_tiff and read_jpeg 1552 1

Hello,
I currently use an IDL 8.3 license. I need to read in an image in TIFF or JPEG format using IDL. I tried using read_tiff or read_jpeg tasks in IDL. Looking at the IDL reference on exelisvis website, it seems like these procedures should be available with IDL 8.3 license. However, it seems like the corresponding procedures do not exist in my IDL library, because I cannot compile the files:

Error opening file: OPENW 4990 2

Hi folks,
I'm attempting to run the LandTrendr model in IDL, and have hit a snag. I have virtually no IDL experience, but was told that since the code is already written and has been tested, I should have very few hiccups. I've made it through a good number of modules, but have hit a breaking point. I don't know if there is enough background provided here for any of you to help my get past this error, but any help you may be able to provide would be greatly appreciated.
Cheers.
This is the error...
