Please help me in generating multiple matrices and calculation

this code is for one matrix X, but I want N = 5 such matrices

N = 5; % No. of matrices
P = 5; % The number of rows
T = 10; % The number of columns

% Duration of projects
D = [4; 5; 3; 2; 4];
excludedcount = D-1;
X = zeros(P,T);

for row = 1:P
   rv = [1, zeros(1, T - excludedcount(row) - 1)];
   X(row, 1 : (T - excludedcount(row))) = rv(randperm(numel(rv)));
end

Add an extra loop to create a 3D matrix:

N = 5; % No. of matrices 
P = 5; % The number of rows 
T = 10; % The number of columns

% Duration of projects 
D = [4; 5; 3; 2; 4]; 
excludedcount = D-1; 
X = zeros(P,T);

FinalArray = nan(N,P,T) ; % pre-allocation
for MatrixCount = 1:5

     for row = 1:P 
       rv = [1, zeros(1, T - excludedcount(row) - 1)]; 
       X(row, 1 : (T - excludedcount(row))) = rv(randperm(numel(rv))); 
     end

     FinalArray(MatrixCount,:,:) = X ; % store it
  end
