Rows in a matrix with a certain outcome

I have a matrix with 16 columns and a large number of rows. In each column, there is one of two outcomes (ex: one column is filled with ones and zeros, another column is filled with 0.4s and 0.6s). I am looking for a function that can count the number of rows in which a combination of outcomes occurs. For example, I'd like to figure out how many rows have ones, .6s, and .7s.

ex:

1 .7 .6 (random numbers 4-16)

1 .3 .4 (random numbers 4-16)

1 .3 .6 (random numbers 4-16)

1 .7 .6 (random numbers 4-16)

1 .7 .4 (random numbers 4-16)

ans = 2

Answer 1

[dpb]

>> sum(ismember(sort(x,2),[.6 .7 1],'rows'))
ans =
   2
>>

Generalize the set looking for instead of using the hardcoded values, of course...
