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.

clc
close all
a=[1 2 3 ; 4 5 6 ; 7 8 9 ]
%size:number of rows & cloumns
[m1, n1]=size(a);
%for loops
for i=1:m1
% i run upto number of rows in x
for j=1:n1
%j run upto number of columns in x
z(i,j)= (-1)^(1+i)* a [1,j] *... ???????????
end
end
disp('output matrix');
disp(z)

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.)
