Getting octave to plot when invoking a function from the command line

Question

I am trying to run a function in octave from the command line. The function is currently run like so:

octave --silent --persist --eval \'functio

Answer 1

The problem is that when you run from command line, when it ends, the plot windows disappear with it.

#! /usr/bin/octave -qf
f = figure;
set(f, "visible", "off")

t=0:0.001:5*pi;
plot(t, sin(5*t)), grid

print("MyPNG.png", "-dpng")

This saves output to MyPNG.png in the directory where it is run.

Then you might open it with a visualization program.

Another option is to add

pause

at the end of the program so it waits for user input to terminate, therefore to close the plot window.

Cheers :)
