Plot 2 function variables with exp and abs

I have to plot this 2 variables function: e^{-|(x,y)|}.

x = sym('x', [2 1]);

f = exp(-abs(x(1),x(2)));

fsurf(f)

set(gca, 'XLim', [-1 1], 'YLim', [-1 1], 'ZLim', [0 2]);

I'm using this code that work perfectly for others 2 variables function but now I have this error:

Error using sym/abs

Too many input arguments.

Error in (line 5)

f = exp(-abs(x(1),x(2)));

What can I do?

Hi @Michele Guaragno

What is ? Is it ?

[Michele Guaragno]

No, it's (x,y). The function's plot is this one:

I've just solve the ploblem putting

f = exp(-sqrt(x(1)^2+x(2)^2));

instead of

f = exp(-abs(x(1),x(2)));
