Question

Im semi-new with matlab, i’ve been using it in my course for a while now, but never really been taken in by it.

I have a vector of quite a large size, it is a sound file to be accurate. I’m required to take every 128 elements from this vector, and add them to a matrix.

So matrix row 1 will contain the first 128 (1-128) elements, matrix row 2 will contain the second 128 (128-256) etc…

How can I go about doing this? I’ve looked up the matlab mathworks help files and havent been able to find anything. I know I can append matrices using z = [x,y] but its not working for me…

Appreciate any help, thanks!

Answer 1

You can do this with the reshape command:

>> A = [1 2 3 4 5 6];
>> B = reshape(A, 3, 2)'
B = 
      1 2 3
      4 5 6
