I would like to transfer the u_real(n) value to the u_Q1(n) array. But, when I am trying to compile it is telling me that the variable u_Q1 is undefined. How can I define that variable as empty vector.
u_real=real(u);
v_real=real(v);
temp = 0;
for n = 1:100
if and(u_real(n)>0,v_real(n)>0)
if n == temp + 1
u_real(n) == u_Q1(n);
v_real(n) == v_Q1(n);
temp = n;
else
d = n-temp;
u_real(n) == u_Q1(n-d+1);
v_real(n) == v_Q1(n-d+1);
temp = n-d+1;
end
end
end

"... transfer the u_real(n) value to the u_Q1(n) array ..."
Looks to me like you are doing the opposite. What is your actual intent?

u_Q1 = [];

u_real(n) == u_Q1(n);
means to compare u_real(n) to u_Q1(n) for equality and have a value of 0 if they are not exactly equal and 1 if they are exactly equal. Then once that logical 0 or 1 is calculated, the result is discarded because the ";" at the end of the line means not to display the value of the expression.
You probably want to use assignment = instead of comparing values ==
