I need a idea to plot in 3-D

I need a example, i can't plot my centripetal equation in 3-D

the equation is

F = m*(v^2/R)

What have you tried that didn't work?

[Ian Samuelsson]

using vectors like (X,Y,Z) is easy to plot, but i can't do using anothers words

%Example:

xv = linspace(-2, 2);
yv = linspace(1/10, 9/10);
[X, Y] = ndgrid(xv, yv);
Z = (X.^2) .^ Y + X + Y;

surf(X, Y, Z, 'edgecolor', 'none');
xlabel('x');
ylabel('y');
zlabel('z');

is exactily that, thank you so mutch !!
