- Workarounds for Octave 4.0.0:
- no containers.Map yet so use new Dict
structure when running under Octave.
- weird error when +FOO/ directory and FOO.m file both exist so
rename types.m to type_utils.m
- no getReport so implement custom stack printer
- workaround weird issue that happens when a class initializer is
called with the first argument of the same class as per
Env(outer, ...). The class is not properly initialized. So for
now, wrap the outer in a cell as Env({outer}, ...)
- missing MException object types so when in Octave, use a global
variable to store the error object.
- missing native2unicode so just use 0xff character for keyword
prefix.
- workaround some function calling/passing differences. For
example, the "@" anonymous function symbol does not seem to work
for conveying an existing function but only for defininign a new
one. E.g. this works:
@(a,b) a+b
but this doesn't
@my_adder_fn.
so just do this:
@(a,b) my_adder_fn(a,b)
- Add Dockerfile with Octave
- Active Travis for matlab implementation using Octave
