source: trunk/src/matlab/rpLibGetDouble.cc @ 135

Last change on this file since 135 was 135, checked in by dkearney, 19 years ago

1) fixed children function in c++'s library module so users can now
search for children by type.
2) adjusted bindings dictionary module for storing lib's to allow caller
to set the key of the value being stored.
3) removed old targets for rappture_interface.o and rappture_fortran.o
from makefile
4) renamed matlab and octave binding functions names to match the module
they came from.
5) adjusted matlab/octave example in examples/app_fermi/matlab
6) added matlab and octave search paths environment variables to
gui/apps/rappture
