Re: I could not understand the behaviors. Sorry!!

Dear Michael

First question was really stupid.  
Sorry for my carelessness.

Second one was Ooooooo!!
This morning I test mkoctfile test by oregonator.cc.
In this case MSVC's  mkoctfile works well even in my
computrr.  Hello.cc was not made again.

Anyway for most case, I use mkoctfile like to speed up
solving the ODE or non linear eq. by fslove.
It is enough to build oregonator.oct. 

The folowing test were carried out in university.

(Some needless lines were omitted.)

Surely it went well.
Thank you and apologized for your spendind your time to
answer my stupid question. 



***********testOrego2.m
## The test of `oregonator'.
x0 = [ 4; 1.1; 4 ];
%t = [0, logspace (-1, log10(303), 150), logspace

t=linspace(0,500,1000);
ts=time();
y = lsode ('oregonator', x0, t);
time()-ts
plot (t,y);

Please do not care the time in testOrego2.m.  This is not
the problem
what I would like to treat here.

I rewrite the below

Thank you for your kindness and patience.
