using fimplicit with an equation

I am trying to create a plot of a 3D implicit function given by :

sin(x + y) + sin(x − y) + sin(y + z) + sin(y − z) + sin(x + z) + sin(x − z) = 0.

The code i have tried so far is:

%this is an mfile that explores and plots a given 3D implicit function %using the fimplicit command x=[-1:0.0001:-0.0001,0.0001:0.0001:1]; y=[-1:0.0001:-0.0001,0.0001:0.0001:1]; z=[-1:0.0001:-0.0001,0.0001:0.0001:1]; fimplicit3(sin(x+y)+sin(x-y)+sin(y+z)+sin(y-z)+sin(x+z)+sin(x-z)=0)

This gives me the error code 'the expression on the left of the equals sign is not a valid target for assignment.

Removing the =0 gives me the following string of errors:

Error using nargin Argument must be either a character vector or a function handle.

Error in fimplicit (line 6) fimplicit3(sin(x+y)+sin(x-y)+sin(y+z)+sin(y-z)+sin(x+z)+sin(x-z))

Any guidance on this command or perhaps a different command i should be using would be much appreciated

I have also tried using f=@(x,y,z) and then my function and get the same error message as before

I've worked out what my problem was. All sorted now
