WebNumerical Gradient. The numerical gradient of a function is a way to estimate the values of the partial derivatives in each dimension using the known values of the function at certain points. For a function of two variables, F ( x, y ), the gradient is. ∇ F = ∂ F ∂ x i ^ + ∂ F ∂ y j ^ . Webdiv = divergence (Fx,Fy) assumes a default grid of sample points. The default grid points X and Y are determined by the expression [X,Y] = meshgrid (1:n,1:m), where [m,n] = size (Fx). Use this syntax when you want to conserve memory and are not concerned about the absolute distances between points. Examples collapse all smart home controller systempasswort
