How to get the correct value from the given matrix?

like this i have one matrix

 a=[194.2015   74.0495    1.0000
  193.9793  124.4735    1.0000
  168.2779   80.5468    1.0000
  191.4042   99.1337    1.0000
  168.7530  108.8447    1.0000]

for this i should get only the first row and remaining should not display this 'a' matrix in loop condition so the 'a' matrix will get change.

 b=194.2015   74.0495    1.0000;

The simplest way is to write

b=a(1,:)
