0 Replies and 2363 Views Chirp-Z transform  2363  0 Started by  Deleted User Hi, I want to implement an inverse chirp-Z transform that will take bandwidth limited frequency domain data as an input and output a given portion of the time domain. Is there any code out there that will help me &91Currently I use a zero-padded iFFT, this is very slow and introduces a lot of noise; any alternative to this would be good&93 Steve

0 Replies and 3022 Views Reading Binary Files in IDL  3022  0 Started by  Deleted User I have a binary file that I need to read into IDL. It has a structure: 80 byte header &91string&93 4 byte &91integer&93 then for as many times as are equal to the above integer: 12*4 byte &91floats&93 2 bytes unused ('padding') What I wish to do is to read in the header, the integer, then read the floating point numbers into arrays of length of the integer. Unfortunately, IDL documentation (and I will not mince words) is absolute crap, and I cannot figure out how to implement...

0 Replies and 2140 Views Pointers in Objects  2140  0 Started by  Deleted User I want to create objects where the size of the data is not known and it is only been set at run time. That can be done with pointers but when you create a pointer as a data members IDL set it to a NULL pointer at initialization and then you cannot change it afterwards. How can I remedy that Johan Marais

0 Replies and 2048 Views 5.6 & OSX: graphics woes: how about Apple's X11?  2048  0 Started by  Deleted User Direct Graphics does not always display properly under Orobor at least on several TiBooks. This example produces nonaccurate graphics: x=findgen(1000) y=cos(x/5) z=xy tvscl,z The way the system behaves makes it look like a rendering problem, but neither hardware nor software rendering works properly. I'm playing with Apple's X11, used for awhile by a colleague with good results. In this case Object Graphics crashes IDL and sometimes even X11 with hardware rendering, but appears s...

0 Replies and 2098 Views funny results for landscape metrics  2098  0 Started by  Deleted User I'm using version 5.5 and I've written a program to calculate various landscape metrics from a random array. I'm getting good results when the size of the random array is (50,50), (100,100), (500,500), but when I make the array (1277,1654) which is the size I need, I get odd results. Below is part of the code and the problematic results, the rest of the code seems to be working fine. patches = max(regions) patch_sizes = 0 for i = 0, patches-1 do begin t = i 1 size = (re...

1 Replies and 2742 Views Playing sound files with IDL  2742  1 Started by  Deleted User I would like to play sound files with IDL. Is this possible I can read and write .WAV format sound files using the READ_WAV and WRITE_WAV subroutines but I can't figure out how to play these files. The actual format of the sound files is not that important to me. Ideally, I would like to be able to play .WAV files but I would be satisfied if I could play any format of sound file. Thanks.

1 Replies and 2330 Views Spawning an IDL application from a link on a webserver  2330  1 Started by  Deleted User I would like to hear from anyone who has already done this or thought about the possibility. If doing this has become fairly common, does RSI have any utilities to facilitate the process At his point I would think that I could bring up a web form to gather all the necessary input parameters, format that information in a file that could then be passed to an IDL program that allows for a 'batch' mode of operation. Thank you.

1 Replies and 2288 Views Conversion to type double -- problem with READS procedure?  2288  1 Started by  Deleted User I have an ordinary ASCII data file formatted in columns with whitespace between them. So, I've been using the IDL 'READS' procedure to import the data into IDL variables. However, after some hunting for errors propagating through the code, I discovered that the 'READS' procedure was truncating the double-precision variables into float variables before storing them in my type double array. (The numbers I'm using have up to 13-digit precision.) I've been trying to find reasonable ways around this,...

1 Replies and 2744 Views IDL and MPI?  2744  1 Started by  Deleted User I am trying to find information on how IDL can be employed over a distributed environment. I have been reading the white paper on multi-threading and saw that: 'In fact, IDL users have already had success with distributed processing with IDL by taking advantage of larger existing frameworks such as PVM or MPI.' I tried to find an example or an example code but was unsuccessfull. Could you suggest a place to look or is anyone having a sample code for this I am trying to see if I can use I...
