How do you calculate numerically gradient?

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. ∇ F = ∂ F ∂ x i ^ + ∂ F ∂ y j ^ .

How do you find the gradient of a function in Matlab?

g = gradient( f , v ) finds the gradient vector of the scalar function f with respect to vector v in Cartesian coordinates. The input f is a function of symbolic scalar variables and the vector v specifies the scalar differentiation variables.

What does the gradient represent?

The gradient is a measure of slope. The greater the gradient, the steeper the slope. When the gradient of two lines are the same, they are parallel .
