how to solve state space eqution with Euler method ?

hello i am trying to solve this eqution

x_diff=A*x+B*U

clc;
clear all;

R=5;L=10e-3;C=10e-6;U=5;

A=[0 1;-1/(C*L) -R/L];
B=[0 1/L];

t_delta=0.1
x=linspace(0,1,20);
size=size(x)
y_0=[0 0]

for i=1:size(2)
  y(:,i)=y_0+t_delta*(A*x(:,i)+B*U)
  y_0=y(i);

end

this code is to solve this eqution x_diff=A*x+B*U but my x is equel to [x1;x2] meaning that i have a 1 raw vecotr insted of 2 raw vectors , any idea how to solve this problem ?
