I have a dataset and would like to create a loop to skip every other row and get the data pertaining to that data. for example:
  • A 1,2,3,4,5,6
  • B 7,8,9,10,11,12
  • C 13,14,15,16,17,18
I would like to write a for loop to get the data in rows A,C, E, G, etc.

If M is your matrix
out=M(1:2:end,:)

That's the variable name. What's the variable type? Most likely a cell array. You can find out by:
class(data9.Location)

If you indeed have a cell array of strings, this should work:
your_data = cellfun(@(x) x(3:end),data9.Location,'uniformoutput',false)

is there a way to sort the column so that all the A's, are together?
