Plot function handle with vector input

Hi guys

This is the first question I ask in this forum. Please bear with me.

I want to make a surface plot of the following function, but I get no output:

fsurf(@(x)(x(1)^2+x(2)^2-x(1)*x(2)))

if I however use the function with standard x,y coordinates MATLAB easily makes the surface plot:

@(x,y)(x^2+y^2-x*y)

So the question is how do I make the surface plot where the input variables comes in vector form?

Answer 1

[Stephen23]

newfun = @(x,y)yourfun([x,y]);
fsurf(newfun)

Could be generalized for any number of inputs:

newfun = @(varargin)yourfun([varargin{:}]);

Thank you for your quick reply - solution works.
