MATLAB: If i have matrix and i want to do this

functionmatrixmatrix manipulation

if i have this matrix
 Matrix_row = [2     4     2     0     0
               3     6     0     0     0
               4     5     0     0     0
               1     2     2     0     0
               1     2     1     1     0
               1     2     2     0     0
               2     3     2     0     0
               2     2     2     0     0
               1     1     1     4     0
              10     0     0     0     0 ]
and i compute this values
 a = [ 8
       9
       9
       5
       5
       5
       7
       6
       7
      10 ] 
 and b = [ 3
           2
           2
           3
           4
           3
           3
           3
           4
           1 ]
 i need to chick like this 
 f = zeros(10,10)
 for k=1:10
  if a(k) + b(k)-1 == 10 if this condition true then 
    go bake to Matrix_row(k) and convert this row to be a binary 
   (the number in Matrix_row shows how many number of ones in this row like
[2 4 2] == [1 1 0 1 1 1 1 0 1 1]
  • when the condition is true , the number in Matrix_row in that row must between the group of ones just one zero
the final solution will be
 F = [ 1 1 0 1 1 1 1 0 1 1
       1 1 1 0 1 1 1 1 1 1
       1 1 1 1 0 1 1 1 1 1 
       0 0 0 0 0 0 0 0 0 0 
       0 0 0 0 0 0 0 0 0 0
       0 0 0 0 0 0 0 0 0 0
       0 0 0 0 0 0 0 0 0 0
       0 0 0 0 0 0 0 0 0 0
       1 0 1 0 1 0 1 1 1 1 
       1 1 1 1 1 1 1 1 1 1  ]
