发帖数: 1081 | 1 Here is an example of surf:
[x,y] = meshgrid(-2:0.1:2,-2:0.1:2);
surf(x,y,)
But Now I want to apply surf to my defined function myFun(x,y)
But I can not say surf(x,y,myFun(x.,y.))
So any suggestion? Thanks. | k**x
发帖数: 2611 | 2 I think the output of your defined function should be in matrix form. | r*******y
发帖数: 1081 | 3 But it is not the way I want. I just define a scalar function of two
variables.
So no way to apply surf to this kind of defined funciton? Thanks.

If your `f' function can only take two variables, you can do the following
to come up with that matrix:
[x,y] = meshgrid(-2:0.1:2,-2:0.1:2);
x1 = x(:);
y1 = y(:);
for k = 1:length(x1)
z1(k,1) = f(x1(k), y1(k));
end
z = reshape(z1, size(x));
surf(x,y,z)
