if isscalar(YourArray) || isempty(YourArray)
total = YourArray;
else
total = 0;
for R = 1 : number_of_rows
for C = 1 : number_of_columns
total = total + SomeValue * YourArray(R,C) * YourDeterminentFunction(YourArray with Row #R and Column #C crossed out)
end
end
end
SomeValue is +1 or -1 but you need to figure out which.

Use a recursive function.
z(i,j)
Determinents and cofactors are scalar. What is your reasoning for storing something there?
(There are reasons to want to store items as you go through, but I suspect your thoughts are about something else completely.)
