This may sound like an odd question but let's say I have the question "how many items fit within a matrix/cell/set, then I assume nchoosek is not the right command to use right?

 Function File: C = nchoosek (N, K)

 Function File: C = nchoosek (SET, K)

Would you rather use sets?

Examples of input

1. m

m =

{

  [1,1] = Chicken

  [1,2] = Beef

  [1,3] = Ham

}

2. attached data file - sourced from http://archive.ics.uci.edu.

nchoosek will tell you either (a) how many independent combinations you can make from a set, or (b) what those combinations are.  I'm not sure exactly what you mean by 'fit within' a matrix/cell/set. That said, nchoosek expects to work on numerical values, not strings, and a set has to be a numerical vector/array, not a cell array

Maybe if you give us a specific example of the input and output you're looking to get with the simplified chicken/beef/ham example, we can provide better suggestions on the mathematical procedures to use.
