I'm running this code. I want to have all iterations saved in Total_all matrix and from that matrix select the minimum value. then display the corresponding matrices in result which show minimum value. the code is below.but the code is giving minValue as a complete row. can any one please check this?
tic;
no_of_machines=7;
no_of_cells=3;
No_of_Parts = 6;
P1=[1 0 0 1 0 1 1;1 1 0 0 1 0 1];
P2=[0 1 1 1 0 0 1;1 0 1 0 1 1 0];
P3=[1 0 0 1 1 0 0;0 1 1 0 0 0 1];
P4=[1 0 0 0 1 0 1;0 1 0 1 0 1 0];
P5=[1 1 0 0 0 1 0;1 1 0 0 1 0 1];
P6=[0 1 0 0 0 1 1;1 1 0 1 0 1 0];
P = [P1;P2;P3;P4;P5;P6];
z = [size(P1,1) size(P2,1) size(P3,1) size(P4,1) size(P5,1) size(P6,1)];
c = [0 cumsum(z(1:end-1))];
a = allcomb(1:z(1),1:z(2),1:z(3),1:z(4),1:z(5),1:z(6));
n = size(a,1);
all_comb_of_routes = cell(1,n);
for k=1:n
all_comb_of_routes{k} = P(c+a(k,:),:);
end
CELL = zeros(no_of_cells^no_of_machines,no_of_machines);
t = 0;
for k = 0:(no_of_cells^no_of_machines)-1 %k=(2187-1=2186)
s = dec2base(k,no_of_cells,no_of_machines);
if length(unique(s))==no_of_cells
t = t+1;
CELL(t,:) = s-'0'+1;
end
end
CELL = CELL(1:t,:);
combination_array=num2cell(CELL,2);% all possible combinations
[r1,c1]=size(combination_array);
for l=1:r1
R=1:numel(combination_array{l});
Z = zeros(R(end),max(combination_array{l}));
Z(sub2ind(size(Z),R,combination_array{l})) = 1;
allCells_array{l}=Z; % machine cell matrix array of all combinations
end
[r2,c2]=size(all_comb_of_routes);
total_all= zeros(c2, numel(allCells_array));
for m = 1:c2
for n = 1:numel(allCells_array)
movement = all_comb_of_routes{m} * allCells_array{n};
total=sum((sum(movement > 0, 2)) -1);
total_all(m,n) =total;
end
end
minValue=min(total_all)
[all_comb_of_routes(m) allCells_array(n) combination_array(n) minValue];
toc;

Undefined function or variable 'allcomb'.
Error in test1 (line 15)
a = allcomb(1:z(1),1:z(2),1:z(3),1:z(4),1:z(5),1:z(6));
You forgot to give us allcomb(). Or, if it's in one special toolbox, then you forgot to list what toolbox(es) is/are required to run your code.

concerning your problem with the minimum:
you can either use
minValue=min(total_all(:));
% if you want/ need the index:
[minValue,IndexminVal]=min(total_all(:));
or use the min command twice
minValue=min(min(total_all));
the result is the same
