Simulation stopped due to out of bounds error

Hi, I'm running the next code into embedded matlab block from simulink, but when I run it, I have the next error message Simulation stopped due to out of bounds error, Enable debugging to pinpoint the location of the error.

I did enable debugging and it keeps pinpoint the line of D(s,:) = inf , until I stopped appears the same error message Simulation stopped due to out of bounds error. Block Embedded MATLAB Function (#19) While executing: none.

Can anyone please help me with this..

x=(54,2);

function D = distmat(X)
%DISTMAT Compute euclidian distance matrix from coordinates

[n,dim] = size(X);
D = zeros(n);
for j = 1:n
  for k = 1:dim
      v = X(:,k) - X(j,k);
      D(:,j) = D(:,j) + v.*v;
  end
end
D = sqrt(D);

%--------------------------------------------------------------

function p = greedy(s,D)

n = size(D,1);
p = zeros(1,n,'uint16');
p(1) = s;

for k = 2:n
  D(s,:) = inf;
  [junk,s] = min(D(:,s)); 
  p(k) = s;
end

Who is calling the function greedy? It looks like the argument 's' is large than 'n' (I'm assuming the second argument D is the same that constructed by the function distmat)

btw, in the matlab promt appear the next message

Runtime error: Expected an integer value, found non-integer variable s with value 0.0318328.

the function greedy is called by the next function

eml.extrinsic('exchange2');

Lmin = inf;
L = 0;
pmin = uint16(0);

for k = 1:m
  % Nearest neighbour tour
  p1 = greedy(s(k),D);
  % Improve tour by 2-opt heuristics
  [p,L] = exchange2(p1,D);

   % Keep best tour  
  if L < Lmin
    Lmin = L;
    pmin = p;
  end

end

% Output
p2 = double(pmin);
L1 = Lmin;

feel free to do any comment, regards!

Ah! So that's the problem. You need to make sure 's' is an integer. You can't index with a non-integer. For example, you can't do:

x = zeros(2);
y = x(0.2);
