Hi!
to define your function you can use the inline() command and then to plot you can use the fplot() command. Your code may look something like this.
f = inline('x^3') % This creates an inline function
fplot(f, [-1, 1]) % This will plot the inline function f from the limits %set in the second input. Then you can edit the plot area anyway that you %would like (add axis labels and a title)
Hope this helps
Cheers,
Rhys

It seems that the function you want to make is the same as fplot.
