Hello,
I want to write a function code that draw a funcion based on the user input.
function plotFunc(f,x_min,x_max)
f is a function handle.
for example I want to draw x^3 from 1 to -1... how can I defin it in the function?

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.
