More info:

I have a matrix of information and I want to pull certain data cells from all the rows beginning with a 20.

Of the rows starting with the number 20, I want the third cell over.

Ex. I want to grab the cells that are bolded.

10 40 50 80

20 40 20 34

30 50 32 50

20 38 40 36

I want to then take those data cells and put them into a 1 lined matrix

a=[10 40 50 80
20 40 20 34
30 50 32 50
20 38 40 36]
c=find(a(:,1)==20)
out= a(c,3)
