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)
fy = diff(f,y)
You can also find the value of parial derivatives by substituting the value -
fx(1,0)
