This is just information.
I have run the bvp4c demo on windows 7 (64 bit) using 32 bit octave 4.0.0 with
odepkg-0.8.5.
(Intel Corei5 2400, 3.1 GHz, with 4Gbyte memory. (not slow but not fast.))
>> demo bvp4c
Each demo took several minutes but finally got solutions.
As Calro wrote, if you need efficiency, it is necessary to polish the code.
