The functions defined include: how good a drummer is sinaA level surface, or isosurface, is the set of all points where some function has a given value. If f is differentiable, then the dot product (∇f )x ⋅ v of the gradient at a point x with a vector v gives the directional derivative of f at x in the direction v. It follows that in this case the gradient of f is orthogonal to the level sets of f. For example, a level surface in three-dimensional space is defined by an equation of the form F(x, y, z) = c. The gradient of F is then normal to the surface. how good am i at mathWebnumGrad: Create function calculating the numerical gradient; numHessian: Create function calculating the numerical hessian; RFF: Evaluate an RFF (random wave function) at given input; ...
