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

vec =[0 0 0 0 0 ];
vec1 = [1 1 1];
