MATLAB: Save part of an array

Question

Hello, For example I have the matrix A = [1 2 3 4 5 6 7 8 9 10…..10000]. And I want to save in a matrix B(k) where B(1) = the first 20 elements of A so B(1) = [1…20], B(2) = [21…40], B(3) = [41…60] etc… Thank you 🙂

Answer 1

Hello Sonarine,

Try for this..

 A = [1:10000];
 for i = 1:length(A)/20
  B(i,:) = A((i-1)*20+1:i*20);
 end

to check the output..

 B(1,:)
 B(2,:)

So on..
