MATLAB: Replace numbers into a vector starts at the center? Looking for general format

replace numbers into a vector starts at the center

Suppose I have a vector vec with the length will be an odd number.
Then I have another vector vec1 with the length is also odd and less than the length of vec.
I want to put the elements of vec1 into vec that starts at the center of vec and go to both sides from the center.
I'm looking for a general format in case when the length is much more larger !!!
How can I do that?
Ex: This is just an example when length(vec) is 5. I know vec(2:4) = vec1
I'm looking for a general format in case when the length is much more larger !!! 
    vec  =  0 0 0 0 0 
    vec1 =    1 1 1
 new_vec =  0 1 1 1 0
Thank you!

Run this
%%


    vec  =  [ 0 0 0 0 0 ];
    vec1 =  [   1 1 1   ];
 new_vec =  [ 0 1 1 1 0 ];
%%
len  = length( vec );
len1 = length( vec1 );
%%
out = vec;
out( (len+1)/2 - (len1-1)/2 : (len+1)/2 + (len1-1)/2 ) = vec1;
and peek
>> out
out =
     0     1     1     1     0
