![]() ![]() Plot then worked very well and was pretty consistent with Matlab after that, but too much else was missing from it to port my project over without considerable effort and a completely new code branch.Īll this said, I think Octave is a very nice tool, but I also believe that it is so considerably divergent from Matlab 2018a that using the two interchangeably is nearly impossible. To make plot() function I did had to do the following: graphics_toolkit ("gnuplot") I started the interactive version of Octave to see what efficacy it had, and plot would not work. So with that, I was kind of dead in the water. It's also missing the notion of a table object. ![]() Like readtable(), which reads in a csv file. Octave is missing many of the functions that are in the Matlab core. Then I switched to the Ubuntu machine with Octave. It produced the correct output which is a plot with four graphs saved as a jpeg and some analysis text to stdout. OCTAVE VS MATLAB FOR MAC MACFirst I tested my code in headless mode with Matlab on the Mac with this command: /Applications/MATLAB_R2018a.app/bin/matlab -nodisplay -nosplash -nodesktop -r "run('mycode.m') quit " I downloaded and installed Octave onto an Ubuntu Mace OS running on VMware on my Mac. Saveas( h, 'out.png', 'png' ) # you can replace 'png' with 'gif' or 'jpg' etc. To do this, set the 'root' figure object to non-visible before plotting anything: set(0, 'defaultfigurevisible', 'off')Ĭoncretely, your code might look like this: gnuplot_toolkit('qt' ) # optional, if run via xvfb-run or the AWS supports an X Display This problem can be worked around if your images are set to non-visible as default, which still allows them to be printed without necessarily appearing on screen. Occasionally OpenGl complains when you try to plot things that are 'offscreen'. graphics_toolkit('qt')), consider running octave via xvfb-run, which simulates a 'dumb' x server. ![]() If you'd like to 'fake' an x display to allow you use of other graphics toolkits (e.g. If your environment does not provide an X DISPLAY, only the gnuplot graphics toolkit will be available. Things to keep in mind and try to work around include the following: * The has been updated to match the reflect made to `psom_demo_pipeline` in release 0.9.Ī more detailed list of changes can be found in the. * The has been updated to reflect the changes made in release 0.9. The default mode is now 'session' for the pipeline manager, and 'background' for the jobs. In this mode jobs run in the background, and they will get interrupted if the initial matlab/octave session is interrupted (which is not the case in 'batch' mode). * A new wiki page providing for PSOM users. ![]() This function should help a lot setting up the configuration of PSOM. It will test step-by-step that the submission of jobs is successful, and provide context-dependent error messages and suggestions if an issue is detected. So far, the only issue that was found was the 'background'/'batch' modes for Octave on Cygwin (Windows). * The PSOM has now been tested on a variety of operating systems (Linux, Windows, Mac OSX), with both Matlab and Octave and with different configurations. If you are using PSOM and find it useful, it is now an excellent time to show your support by filling in an evaluation on the NITRC website: This will be made avaiable on the PSOM website upon acceptance. A paper of PSOM has also been submitted for publication, with a detailed description of the PSOM design and implementation. This is the PSOM candidate release, with all the features planned for PSOM 1.0 available. PSOM r0.9 had just been released and can be downloaded from here: Tool/Resource: Pipeline system for Octave and Matlab ![]()
