MATLAB: How to delete a row in a matrix

deleting observationsdeleting rows

Hi!
How would I delete all the rows that have a zero in the second column? For example, if I have the matrix
[1 3;2 0;3 11;4 8;5 0]
how could I delete the two rows containing zeroes to make my matrix look like
[1 3;3 11;4 8]
Thank you!!

>> a = [1 3;2 0;3 11;4 8;5 0]
a =
     1     3
     2     0
     3    11
     4     8
     5     0
>> a(a(:,2)==0,:) = []
a =
     1     3
     3    11
     4     8
