3D graph F(x y z)

Hello, I'm trying to draw this function(F) on Mathlab, but I don't know which command to use.

L = (3/2).*(1E-10);

figure [x,y,z] = meshgrid(0:L/50:L,0:L2/50:L,0:L3/50:L);

F=sin(x)*sin(y)*sin(z)

Thank you for your help

Hi Lex, you haven't told us what L2 or L3 is here, but you have a few issues.

First

L = (3/2).*(1E-10);
0:L/50

What do you think the above creates? This will simply be 0 because you are saying "give me a vector which increments from 0 to basically 10^{-10} in steps of 1. So that will just give you a zero.

The other problem is that on the face of it you are creating an NxMxK array and a 3D plot is only going to work if your ultimate output

 F=sin(x).*sin(y).*sin(z);

Is 2-D or a NxMx3 matrix.

Thanks L=L2; L=L3;

Alright, using

F=sin(x).*sin(y).*sin(z);

which command should I use to plot the graph ?

You did not address the fact that you are creating an "array" that consists of just 0. See my questions above.
