Hello, You can use diff function operator to obtain partial derivatives as follows:

1- Define the function using symbolic variables

%Random function for example
syms x y;
f(x,y) =  x^2 + y^2 + x*y;

2-use diff with respect to the variable you want to differentiate.

fx = diff(f,x)

fx(x, y) = 

fy = diff(f,y)

fy(x, y) = 

You can also find the value of parial derivatives by substituting the value -

fx(1,0)

ans =
