Plotting 4dimentional data error

Hi all I'm trying to plot the data to see the global minimum point. I'm presented with the equation
C = (1.10471.*((Z).^2)*((X).^2))+(0.0481*(Y*Z)*14*X);
my first issue is that when I try to produce a plot of this I get the error
??? Error using ==> mtimes Inputs must be 2-D, or at least one input must be scalar.
Error in ==> Untitled4 at 5 C = (1.10471.*((Z).^2)*((X).^2))+(0.0481*(Y*Z)*14*X);
My code is x = -10:1:10; y = -10:1:10; z = -10:1:10; [X,Y,Z] = meshgrid(x,y,z); C = (1.10471.*((Z).^2)*((X).^2))+(0.0481*(Y*Z)*14*X); surf(X,Y,Z,C); hold on; axis([-10 10 -10 10 10 10]);
Many thanks

))+(0.0481*(Y*Z)*14*X);
))+(0.0481*(Y.*Z)*14*X);
Note difference:
doc vectorize
to avoid these errors in the future.

Whenever you get a error using {mtimes, mrdivide, mpower, mldivide}
and you don't want to be doing element-by-element multiplication.
