Plotting Anonymous Function of two variables

Hello,
I have defined the following Anonymous Function of two variables:
f1 = @(x) erf(x(1))+cos(x(2));
When writing the command for plotting via fsurf
fsurf(f1,[-5 0 -5 5])
I get the following warning and my figure remains empty:
Warning: Function behaves unexpectedly on array inputs. To improve performance, properly vectorize
your function to return an output with the same size and shape as the input arguments.
So, what am I doing wrong?
I know that I can plot the function with
f1 = @(x,y) erf(x)+cos(y);
fsurf(f1,[-5 0 -5 5])
but I want to plot it like at the beginning.
How can I plot a Anonymous Function that is defined as mentioned at the beginning?
Regards,
Michael

"the objective function has to be defined as mentioned"
I am bit skeptical about "has to".
Can you give more details about what you are trying to? Can you share the objective function?

f1 = @(x) erf(x(1))+cos(x(2));
fsurf(@(x1,x2) f1([x1,x2]) , [-5 0 -5 5])
