#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
