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'.
Now I would like to calculate the gradient for the this histogram at each point. So this would actually mean I have to calculate the gradient for a 1D function at certain points. However I do not have a function. So how can I calculate it with concrete x and y values? For the sake ...
Create the function f(x,y)=x2+y2 using a function handle. f = @(x,y) x.^2 + y.^2; Approximate the partial derivatives of f(x,y) with respect to x and y by using the gradient function. Choose a finite difference length that is the same as the mesh size. ...
We have a function which is a sum of polynomial functions and an exponential function. We will find the gradient of the function using the partial derivatives. Then we will do its dot product with the unit vector along ...
