so basically i want to do this:
syms E1(x,y,z) E2(x,y,z) E3(x,y,z)Ecurl=symcurl(x,y,z,E1,E2,E3)function Ecurl = symcurl(x,y,z,E1,E2,E3)Ecurl1 = diff(E2,z)-diff(E3,y)Ecurl2 = diff(E3,x)-diff(E1,z)Ecurl3 = diff(E1,y)-diff(E2,x)Ecurl=[Ecurl1 Ecurl2 Ecurl3]end
with the builtin curl function of matlab. When i try it like this:
syms x y z E1 E2 E3curl([x,y,z],[E1,E2,E3])
i get a zero vector. And like this:
syms E1(x,y,z) E2(x,y,z) E3(x,y,z)curl([x,y,z],[E1,E2,E3])
i get an error message that the second argument must be a vector of three variables. In the end i want to be able to use the subs command to assign a specific function to E1 E2 E3 at a later time. Thanks.
