How to get the output result from a jacobian as this.

I was trying to get the number result from the jacobian by define X1 to X7 after I found the jacobian in X1 to X7 term as the code show. How can i do this?

clc
clear
accept_error = 0.001;
maxiter = 50;
P = 20;
dx = 0;
X0 = [0.5;1;0.5;0;0;1;1];   %Initial Guess
syms X1 X2 X3 X4 X5 X6 X7
F = [0.5*X1 + X2 + 0.5*X3 - X6/X7; 
     X3 + X4 + 2*X5 - 2/X7;
     X1 + X2 + X5 - 1/X7;
     -28837*X1 - 139009*X2 - 78213*X3 + 18927*X4 + 8427*X5...
     + (13492/X7) - 10690*(X6/X7);
     X1 + X2 + X3 + X4 + X5 - 1;
     (P^2)*X1*(X4^3) - 1.7837*(10^5)*X3*X5;
     X1*X3-2.6058*X2*X4];
jac = jacobian(F,[X1,X2,X3,X4,X5,X6,X7]);
X1 = X0(1); X2 = X0(2); X3 = X0(3); X4 = X0(4); X5 = X0(5);
X6 = X0(6); X7 = X0(7);
Result = jac;  %%%???

jac = subs(jac,[X1,X2,X3,X4,X5,X6,X7],[X0(1),X0(2),X0(3),X0(4),X0(5),X0(6),X0(7)])
