Hello. I want to calculate the gradient of the function : g={@(x)-x;@(x)x-1;@(y)-y;@(y)y-1}; with the following command : gradient(g, [x, y]); but I get the following error : Undefinedfunction or variable 'x'.
Gradient of a Function: Consider a two-variable function z=f(x,y) which represents some smooth surface. The gradient of this function gives a vector representing the maximum rate of change and is perpendicular to the surface and pointing outwards. Mathemat...
Calculate the gradient ∇f of the function f(x, y, z)=r=x2+y2+z2. Gradient of a Scalar Function: The gradient of a scalar function at any point is a vector function, whose magnitude gives the rate of change of a scalar function with the distance...
jacobian(Symbolic Math Toolbox)generates the gradient of a scalar function, and generates a matrix of the partial derivatives of a vector function. So, for example, you can obtain the Hessian matrix (the second derivatives of the objective function) by applyingjacobianto the gradient. This exampl...

First of all, I assume that this is a low Re number wall function, otherwise the wall shear stress is not directly connected to the velocity gradient at the wall (if this is gibberish to you, then you need to research nutkWallFunction and wall functions in general). ...
As a workaround, given: F = matrix of F values varying along r and theta r = vector of radius values theta = vector of radian values the following code can be used to calculate the gradient. % Take the gradient of F, suppose that the values o...
