I have two probability density functions related to two variables
f(1) = 2.*2.5.*(((x(1)-1.6580)./0.5).^1).*((1-(((x(1)-1.6580)./0.5)).^2)).^1.5;
f(2) = 1.5.*3.5.*(((x(2)-1.8128)./0.3).^0.5).*((1-(((x(2)-1.8128)./0.3)).^1.5)).^2.5;
How to plot joint probability function using f(1) and f(2).

It depends on exactly what you want to plot, but you could try either the plot3() or contour() command.
