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'.
grad= gradient(fcnAppx,lossFcn,inData,fcnData)evaluates the gradient of a loss function associated to the function handlelossFcn, with respect to the parameters offcnAppx. The last optional argumentfcnDatacan contain additional inputs for the loss function. Examples collapse all Calculate Gradients ...
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∂xˆi+∂F∂yˆj . The gradient...
Nonparametric density gradient estimation using a generalized kernel approach is investigated. Conditions on the kernel functions are derived to guarantee asymptotic unbiasedness, consistency, and uniform consistency of the estimates. The results are generalized to obtain a simple mcan-shift estimate that ca...
