This page is to a large extent obsolete, as most of my useful octave code is on Octave-Forge

Octave links

Mighty Octave's home page

Octave is a numerical language, to some extent compatible with Matlab", but free.

Octave-Forge

Octave-Forge is a separate and quickly evolving repository of Octave functions and links. This site provides a toolbox that complements Octave's native functions.

Oldies

Most of the links below have been ported to Octave-Forge, so they may be obsolete. I keep them here because some have not been ported yet (if ever) and may provide some specific functionality.

Note : Some of the functions above may be dependent on other functions that are not in the tar file. If that happens, ask me for the missing functions.

Patches for Octave 2.1.34

octave-2.1.34.leval.patch Patch for a 'leval' built-in function. 
  res = leval ("funcname", arglist)
Where "funcname" is the name of a function and 'arglist' is a list variable. "funcname" is called with all the elements in 'arglist' as arguments.

This is the same as 
 res = eval (["funcname", "(",               \
	        nth(arglist,1),",",          \
                ...,",",                     \
	        nth(arglist,length(arglist)),\
                ")"]);
but quicker. This function is used in the optimization functions above.

octave-2.1.34.kron.patch Built-in 'kron' function. Speed-up wrt. to original is more or less a factor of 5.

octave-2.1.34.exist.patch Patch so that 'exist' functions may accept to be called as 'exist("myvar","var")'. It will return 1 if there is a variable called myvar and zero otherwise. The advantage over 'exist("myvar")==1' is speed : the later checks for functions and files called "myvar" and that takes time.
