What I want to do is insert a certain value in between every second value of this vector.

However if I continue like this my code will get very long and also since the length of the original array can change I'll be in trouble. Can anyone explain a way to do this by using a loop? I get very confused with the use of loops! > > How about: > offset=[offset;5*ones(1,length(offset))]; > offset=offset(:)';
That will insert one 5 in every second position. However I want to insert more than just one value (127 actually) every second position. Is it possible to adjust your code to accomplish this? Thanks
