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

it can be defined mathematically as
δD/δf

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).
