Info

In short, once you  you have realised this plot, you will have understood and used the main concepts of Magic

 

 

Before you start ...

During this tutorial, you will use python Python and magicsMagics++ on a linux Linux workstation.

Here is a list of basic commands you may need want to use.

Basic

...

UNIX commands:

  • ls : list the files in the current directory
  • mkdir my_exercise : create a directory called my_excercise
  • cd my_exercise :  go to the directory my_excercise. my_excercise becomes the current directory

...

There are several editors available

  • vi :
  • emacs
  • kate
  • nedit
  • geany ( python Python syntax highlighted..)
Run the python interpretor :

In this tutorial we are expecting you to create a python script using your favourite editor and run python to interpret it. Your system have been set-up already and you can use Magics and python by typing the single command:

python magics.py 

Visualise your result:

Magics will generate a postscript Postscript or a png PNG output. To visualise the results, you can use one of the following commands:

  • gv magics.ps : visualise a postscript Postscript file called magics.ps
  • xv display magics.png : visualise a postscript PNG file called magics.pngdisplay
  • xv magics.png : visualise a postscript PNG file called magics.png
