source: trunk/src/octave/rpPutDouble.cc @ 122

Last change on this file since 122 was 122, checked in by dkearney, 17 years ago

added initial version of octave language bindings.
1) no claiming language bindings work, but will happily take credit if they do.
2) bindings are untested
3) bindings happen to work with mystery example that happens to be located in examples/app-fermi/matlab/fermi_rp.m and happens to be invokable with examples/app-fermi/matlab/tool_rp.xml
4) bindings need octave2.1-headers installed (in debian: apt-get install octave2.1-headers) to get the mkoctfile program
5) binding function names might be changing to be more discriptive and more tightly bound to either the lib or units module.
6) adjusted Makefile to add octave bindings compilation.
