Re: Running external program from Octave

[Lester Anderson]

Kind of works:

>> y = dos('grdfft test2.grd -Gout.grd -D')
grdfft: Warning: The z-range, [-2.40962e+008,4.8311e+008], might
exceed the significand's precision of 24 bits; round-off errors may
occur.
y = 0
>>

Ignore the warning bit, this was a random test, but why does it return
a value of 0 ?
