Three-dimensional plots typically display a surface defined by a function in two variables, z = f(x,y). If you know more about your function and can turn it around into a function of only one variable (e.g., sine and cosine of t), that is preferable in most cases. contour (Z) creates a contour plot containing the isolines of matrix Z, where Z contains height values on the x - y plane. Your equation x^2 + y^2 + z^2 = 1 resembles a surface and can be plotted with the fsurf command in MATLAB which will need your function handle as an argument. Plotting X Y Z. 6.5.7 Plotting functions z=f(x,y) The plot of a function z = f(x,y) is done by plotting the triples of points (x,y,f(x,y)), just as the plot of the function y=f(x) is the plot of the pairs of points (x,f(x)).
