Best Answer

On the other hand, maybe you want to subtract row 2 from all the rows. In that case, you can do this.
>> A
A =
     1     2     3     4
    11    12    13    14
    22    23    24    25
    42    43    44    45
>> AsubRow2 = A - A(2,:)
AsubRow2 =
   -10   -10   -10   -10
     0     0     0     0
    11    11    11    11
    31    31    31    31
