How to plot a function (graph)?

[Robb Bean]

Hi!

Yesterday I started programming in Octave using a Matlab tutorial which 
was very helfull, I did not expect Octave to be so close to the 
"original". But I missed a function for plotting a function graph; 
Matlab contains the fplot function, which does not exist in Octave. 
Here is what I had to code:

__gnuplot_plot__(['[x=0:1] ', num2str(a), '*x*(1-x)'])

The Matlab way of doing this should be something like this:

% a is a global variable

function ret = f(x)
    ret = a*x*(1-x)
endfunction

fplot(@f, [0 1])

(See 
http://www.mathworks.com/access/helpdesk/help/techdoc/ref/fplot.html 
for details.) Did I miss something or is there really no fplot 
equivalent in Octave?

Yours,
