Gradient of a function at specific x,y,z values in Mathematica

WebIn mathematics, the gradient is useful to know the angle between two lines. Generally, one of the lines is considered to be the horizontal line parallel to the x-axis or the x-axis and the angle it makes with the other line is referred to as the gradient of that line. If the angle between the lines is θ θ then the gradient m= tanθ m = t a n θ. WebIn this article, a new numerical gradient scheme based on the collocation polynomial and Hermite interpolation is presented. The convergence order of this kind of method is also O ( τ 2 + h 4 ) under the discrete maximum norm when the spatial step size is twice the one of H-OCD, which accelerates the computational process. ...
