Sphere function测试函数
WebThe surface harmonic Q† is a solution of the equation. (3.4) or otherwise formulated, Q are the scalar eigenfunctions of Laplace operator on the surface of a hypersphere of a unit-radius (i.e. in the three-dimensional space with the metric ( 2.12 )). Equation (3.4) can be readily obtained, e.g. from the four-dimensional Laplace equation: Web29. máj 2013 · I tried plotting a sphere to look like this. This earlier question contains the code where i tried plotting. That previous question was answered, but now I am having trouble plotting the sphere function as shown in the plot given by the link above. Edit This is the sphere function i am using: function ph = sphereFN(x) ph = sum(x.*x, 2); end

Web3. Sphere is a level set of the function F ( x, y, z) = x 2 + y 2 + z 2. For example, F ( x, y, z) = 1 corresponds to the sphere of the radius 1. Being a 2-dimensional object one can locally re-parametrize it with two independent coordinates, for example in the top semi-sphere, simply by x, y, from which z = 1 − x 2 − y 2. Share.
