Undefined function or variable 'y'.
Error in Untitled (line 5)
y = exp(x.^2+y.^2);
my computer gives these errors and I do not know how to fix them.

Try this:
fsurf(@(x,y)exp(-(x.^2+y.^2)), [-2 2 -2 2])

Can you also suggest for me what range would i change if i want to draw the function f(x,y)=(x^(2)+y^(2)) ℯ^(y^(2)-x^(2))
The proof of the pudding is in the eating.
