view liboctave/numeric/ODEFunc.h @ 30508:6f07492c9c20 stable
Provide header file with forward declarations of matrix types (bug #59820).
* liboctave/array/mx-fwd.h: New file.
* liboctave/array/module.mk: Add new file to build system.
* other files in liboctave: Include mx-fwd.h instead of forward declaring matrix
types.
