Im having trouble plotting a trinomial graph, for the function y = x^3. I wrote out the function and tried the plot command but it wont work really.

fun = @(x) x^3;
fplot(fun,[-3,3])
Alternatively:
x = linspace(-3,3);
plot(x,x.^3); % Note the use of .^, for element by element operation as opposed to matrix operation
Please type
doc fplot
doc linspace
doc plot
for more details.
