How to compute the gradients of the the Neural Network in matlab

If we have a nural network: y = f(x,u), then how to caculate the dy/du or dy/dx in matlab? Is there any tool in matlab?

Hi Hanqiu,

Refer to dlgradient-MATLAB for gradient calculation.

The function takes in y-(Variable to differentiate) and x1,x2....xk (Variable in function) and returns the gradient (dydx1,dydx2,...dydxk) corresponding to the variables in function.
