I need the ability to generate contour plots with labeled contours.
From my search on octaveforge, I have found that the "function"

prepared
for the comment "why don't you implement it?"
What would it take to implement this feature? Is it just "code" to be
implemented, or does it require an intimate knowledge of the guts of
octave? If it is just "code" then if someone could point me in the
right direction, I will take a look at it. If it is the later,
well, I
guess I'd like to formally request the feature. At this point I can't
even get octave to find libpcre despite adding it to LDFLAGS. :(

I've only taken a glance, but it appears to me that the labels can be
added without intimate knowledge of the guts of Octave.
You might begin by looking at contour.m and __contour__.m
Regarding your problems building, what OS are you using? and exactly
what was the syntax you used to configure Octave?
Ben
[Labitt, Bruce] Thanks for the tip on contour. I'll take a look at it.
I think I have solved the build problem. Although I had LDFLAGS
pointing to the correct directory, ld could not find the libraries. I
had to add a file to /etc/ld.so.conf/ to get ld to be able to find
lpcre. Then the linker could not find libfftw3 so I had to add a
LD_LIBRARY_PATH statement to tell it an additional place to look. I
don't know why it was so painful - but it is done. My OS is Scientific
Linux 5.2, a RHEL clone. The OS was a fresh install rather than an
incremental upgrade.
Regards,
Bruce
