To perform central finite differencing of a multivariate function in MATLAB, you can use the gradient
function. This function computes the numerical gradient of a scalar function of several variables using central differences.
Here's an example:

In this example, we defined a simple function f
that takes two variables x
and y
. We then used the gradient
function to compute the partial derivatives of f
with respect to x
and y
at the point (x0,y0)
. Finally, we computed the numerical gradient using the central difference approximation formula.
