MATLAB: Replace an element in a vector with another element.

vector

I want to replace the elements of a vector with an element from other vector. But the real glitch here is that i just want 4 values from that vector to be activated and replaced.
So the code goes like this:
g=[1 2 3 4 5 6 7 8 9];
u=[1 1 3 5 4 3 7 8 9];
gout =g;
active_g = [2 3 5 6];
active_u = [2 3 5 6];
U = (g(active_g)>u(active_u))
gout(U) = u(U);
gout(~U) = g(~U);
Now the output should be gout = [1 1 3 4 4 3 7 8 9] But due to U becoming a 1*4 vector.. its not updating elements after that. Kindly suggest a way around. I just need to update the active elements and send it to other function as input but at the same time i need the complete g to evaluate another function.
So its like input g -> function(g,l) -> function (g_updated).

Best Answer

g=[1 2 3 4 5 6 7 8 9];
u=[1 1 3 5 4 3 7 8 9];

gout=min([g;u])

gout =

       1     1     3     4     4     3     7     8     9
