I have an n x 5 cell array, the 5th column is a logical (0 or 1).
I want to split this into two separate cells, one for false(0) and one for true (1), preserving the cell structure.
What's the best was of doing this?

You can treat your cell array like a matrix. So if X is your nx5 cell array,
truecells = X([X{:,5}],1:4);
falsecells = X(~[X{:,5}],1:4);

Sorry I'm not sure what you mean by "won't do anything". That line of code basically splits your original cell array into two cell arrays based on whether the 5th column was true or false.

@Stephen Thompson: based on the description in your question, Kaushik Lakshminarasimhan's answer fulfills your needs. What does "won't do anything" actually mean?
truecells = X([X{:,5}],:);
falsecells = X(~[X{:,5}],:);
