How to find the numerical partial derivative of matrix

Hello Matlab Community

I want to find the partial differentiaton of a particular column from a matrix. For instance

D =

0.9293 0.4733 0.9172 0.5678 0.9340

0.3500 0.3517 0.2858 0.0759 0.1299

0.1966 0.8308 0.7572 0.0540 0.5688

0.2511 0.5853 0.7537 0.5308 0.4694

0.6160 0.5497 0.3804 0.7792 0.0119

f =

0.4733

0.3517

0.8308

0.5853

0.5497

D is a 5x5 matrix and f a 5x1 matrix obtained from the second column of D.

I want to compute a partial differentiation of D with respect to f or the second column. Your input is highly appreciated. Thanks in advance

Could you show how "a partial differentiation of D with respect to f" is mathematically defined ?

[Evans Gyan]

it can be defined mathematically as

δD/δf

[Torsten]

Interesting. Can you give an example ?

See if the gradient (link) function will do what you want.

You will probably have to experiment with it, since I do not understand what you want to do (i.e. how you intend to calculate the derivative).

[Evans Gyan]

After careful studies from the gradient function, i am able to fix the problem. Thank you guys

[Star Strider]

My pleasure.

If my Answer helped you solve your problem, please Accept it!

Could you please share the code solution using gradient? thank you.
