State space representation coming out incorrect

Struggling on a homework problem. The question is

My code is: q= 1 *10^-9;

m= 1 *10^-6;

g=[0;0;-1.6];

E=[1.23,0,10];

B=[0;0;36.13 * 10^-6];

v=3.2;

x_0=[0;0;0;v*cosd(45);0;v*sind(45);0];

A=[0,0,0,1,0,0,0;0,0,0,0,1,0,0;0,0,0,0,0,1,0;0,0,0,0,(q/m) * B(3),(-q/m) *B(2),0;0,0,0,(-q/m)*B(3),0,(q/m)*B(1),0;0,0,0,(q/m)*B(2),(-q/m)*B(1),0,0;0,0,0,0,0,0,0];

B=[0;0;0;(q/m)*E(1);(q/m)*E(2);(q/m)*E(3);1];

x_dot=(A*x_0)+B

My answers are coming out incorrect. Where is the error?

First, make sure your units are consistent. v is given in km/s. g is in m/s^2 (though you don't seem to have used g!).
