== Programs, Libraries, and Packages == | |||
Recipes for developers of Octave programs and libraries. The type of stuff | |||
an Octave programmer should be aware when writing code for others. | |||
=== Find Octave configuration === | |||
Octave can be built with many configurations so programs may end up running | |||
in a machine without features they need. Developers should never expect an | |||
Octave installation to have all features. And programs should identify if | |||
the required features are available. | |||
This is a list of possible tests to check for features: | |||
## support for 64 bit indexing | |||
sizemax () > intmax ("int32") | |||
## built with support for java | |||
usejava ("jvm") | |||
## support for image IO | |||
try | |||
[~] = imformats (); | |||
image_io_support = true; | |||
catch | |||
image_io_support = false; | |||
end_try_catch | |||
