Can you please explain a little more:
1. GNUPLOT:
Terminal type set to 'aqua'
gnuplot> plot sin (x)
In gnuplot this produces y = sin(x) using default x = (-10:?:10) (? Because
I don't know what the default spacing is), default y from -1 to +1.
2. OCTAVE WITH GPLOT:
octave:1> gplot sin(x)
error: `x' undefined near line 1 column 11
x = (-10:0.1:10)';
(Complex Conjugate Transpose Operator "'" and ";" for suppression of output;
I assume that Transpose Operator ".'" would work also)
octave:2> gplot sin(x)
Produces y = sin (x) with x = 0-200 but it must correspond to -10 to +10 and
showing 20/6.28 = 3.2 full cycles. Default y is -1 to +1.
3. OCTAVE WITH MATLAB-LIKE plot(y):
octave:5> plot (sin(x))
Again x has to be defined but was already defined above. Almost identical
results as in 2. X-axis goes from 0-250 but sin (x) is only drawn as far as
200. Default y is -1 to +1.
4. The Octave manual defines "gplot" as a low-level (plotting) function and
"MATLAB-like-plot" as a higher-level plotting function. Gnuplot handles the
actual graphics in both cases, so what does "low-level" and "higher-level"
refer to?
Thanks, Henry
