ode2



Dear Maxima,

I installed Maxima and wxMaxima in Ubuntu, but when I ran an ode2 command, I got problem as below:
> ode2('diff(y,x,2)+'diff(y,x)-6*y=0, y, x);
>
Could not find `ode2.mac' using paths in file_search_maxima,system.#0:
ode2(?_l=['diff(y,x,2)+'diff(y,x,1)-6*y = 0,y,x]) -- an error.  To
debug this try debugmode(true);

Could you give me solution?
Thank you for your attention.

Yours sincerely,
Munadi
