how to delete particular row in given matrix?

like this ('a' and 'b' will get varies;in this row will get varies and column is constant)

 a=[181.2033  169.4197    1.0000];
b=[86.2558  191.0205    0.9994
  136.4055  194.7999    0.9992
  181.2033  169.4197    1.0000
  191.3842  193.7259    0.9983];

than the answer should be

 c=[86.2558  191.0205    0.9994
  136.4055  194.7999    0.9992
  191.3842  193.7259    0.9983]

i should delete a row of 'a' in 'b'

Use the setdiff function:

c = setdiff(b, a, 'rows');

This gives you the result you want.
