Hi guys, I am working on the 4D assignment problem.

I have to fill the set of persons to the roles under each department in different companies,

eg. assign John to HR officer under HR department in Company A.

Each companies share the same set of departments and roles.

And each persons have their own value on the sets of roles.

I got the data but how do I create this kinds of 4D Array in the efficient way?

u need to use the function cat like this:

T1=%the first array T2=%the second array T3=%the third array T4=%the forth array

4D_array= cat(4,T1,T2,T3,T4); %4 is the number of dimensions and T1..T4 are the arrays

or u can take a look at this https://www.mathworks.com/help/matlab/math/multidimensional-arrays.html
