Introduction

What’s EpsTk ?

(see logo.png)

It’s a set of graphical output functions for Octave and Matlab® written by stefan..nosp@m.mueller@fhr.frau.nosp@m.nhofer.de.

This toolkit is a solution of my big problem that I had 1997.

I needed graphical output functions for programs which ran with

Octave (a freeware Matlab-clone on Unix(Linux)-sytems) and Matlab.

But I could not find any tool in the internet.  So, I wrote this tool myself.

The toolkit consists of some matlab functions, which generate graphical

outputs with postscript commands.

To convert the generated postscript files in bitmap formats you can use

a postcript interpreter like Ghostscript (freeware for all systems).

Summary

Features

  • MATLAB®-Code(4.3) with graphical output functions runs in Matlab and Octave
  • All functions are pure m-files
  • Most 2D scientific graphics functions are written
  • Modifications and extensions are no problem
  • Generated EPS-files are very small and importable with no loss of quality
  • WYSIWYG (with Ghostview or a Browser)
  • Freeware (GPL)

Difference to version 2.3

  • new function ecolor2gray added
  • linewidth bug fixed
  • scale bug fixed

Requirements

  • Matlab (>3.x) or Octave (>2.x)
  • Ghostscript
  • Browser (eg.  Firefox)

Installation

  • Include the epstk-mFile-directory in the octave-path or matlab-path
  • Edit file ‘einit.m’ in epstk-directory to set the Parameter ‘ePath’, ‘ePsdPath’, ‘eDocUrl’, ‘eBrowser’, ‘eGhostscript’ and if you need ‘eGhostview’,.

Testing

  • Start matlab or octave
  • Start ‘edemos’ or the single samples:’edemo1’(Simple plot), ‘edemo2’(Standard plot), ...  ,’edemo17’(Encoded text) If all demos works, epstk should be ok.

Write ‘hello world’ program

Type the next line in octave or matlab !

eopen;etitle('hello world');eclose;eview

Write simple plot program

eopen;eplot(rand(100));eclose;eview
