What is it?

Octave-Wcalc refers to the Octave interface to the wcalc routines. This interface allows the user to apply the full power of a high level programming language like Octave to the design and analysis of the various Wcalc supported structures. For example, it is extremely simple to plot the Q and self resonant frequency of a 220 nH inductor as a function of winding diameter or to optimize the impedance of a microstrip line to produce minimum loss. For quick calculations with only a few sets of parameters, the standalone GTK-Wcalc is a simpler tool, but when complex optimizations or plotting is desired, the Octave interface provides tremendous flexibility.

Compiling Octave-Wcalc

If you are using octave version 3 or later, then the mex capability should be built in. If you are using an older version of octave then to compile and use Octave-Wcalc you must install the Octave mex package which is part of the Octave-Forge package for Octave.

Using Octave-Wcalc

Loading Octave-Wcalc (After Installation)

To use the Octave interface, the octave-wcalc files must be in your octave search path.

Loading Octave-Wcalc (Before Installation)

If you want to try out Octave-Wcalc before it is installed in its final location, use the runoctave script which ensures that octave can find the shared libraries required by wcalc.

Running the Octave-Wcalc Functions

Once the Octave-Wcalc interface has been loaded, the Octave-Wcalc functions appear as Octave builtin functions. Complete documentation on the various functions is available via Octave's online help.
