#Day4- #100DaysChallenge- Matlab Loops| Find Most Non zeros Row in a matrix

#Day4-Find Most Non-Zeros Row in a matrix

Task: Find Most Non-Zero Rows in a given Matrix

Note: This code can be done using the in-built command. But for the challenge I am trying to avoid those.
a=[1  2  4 5 0
     0  2  3  0  0
     3  4  0  0  0
     0  0  0  0  1]
If the above matrix is given then the code has to return as 1 which means Row 1 has most non zero entries.

Matlab code:
function r = fullest_row(a)
  [m,n]=size(a);

 
 
  for i=1:1:m
      vec(i)=0;
      max_value=0;
      for j=1:1:n
          if (a(i,j)~=0)==1
              vec(i)=vec(i)+1;
          end
      end
  end
 
  for ii=1:1:m
      if max_value<vec(ii)
           max_value=vec(ii);
           r=ii;
      end
  end
end

Sample Input and Output

a =

     3     0     0     0
     3     3     3     0
     5     0     0     2
     1     0     0     0
 r = fullest_row(a)

r =

     2
