MATLAB: Fill a matrix with same values

Question

Hi! I have a matrix like this:

   [ 1 8 9 7 7 4]
   [ 0 0 0 0 0 0]
   [ 0 0 0 0 0 0]
   [ 9 8 6 5 5 1]
   [ 0 0 0 0 0 0]

And I want to fill it like this

   [ 1 8 9 7 7 4]
   [ 1 8 9 7 7 4]
   [ 1 8 9 7 7 4]
   [ 9 8 6 5 5 1]
   [ 9 8 6 5 5 1]

It seems to be very easy, but I cannot realize how to do it. Thank you in advice!

Answer 1

Another way,

e=find(any(A,2)); 
[h,b]=histc(1:size(A,1),[e;inf]);
A=A(e(b),:);
