Different variable type when using function

I thought I managed to make everything working decently but after searching for any error one thousand times, I found one in one of my functions.

So, I have this function:

function [path, amountofpaths, dist_parc] = caminhos(origem, prev, valores_adj_final)

clc;
amountofpaths = length(prev);
path = cell(1, amountofpaths);
dist_parc = cell(1,amountofpaths);

for i = 1:amountofpaths
    if ~(origem == i)
        a = prev(i);
        path{i}(1) = i;
      b=2;
      while a ~= 0
          path{i}(b) = a;
          a = prev(a);
          b = b+1;
      end
  end
end

for i = 1:amountofpaths
  path{i} = flip(path{i});
end

for i = 1:amountofpaths
  if length(path{i}) == 2
      for j = 1
          dist_parc{i} = valores_adj_final(path{i}(j), path{i}(j+1));
      end
  end
  if length(path{i}) > 2
      for j = 1:length(path{i})-1
          dist_parc{i}(j) = valores_adj_final(path{i}(j), path{i}(j+1));
      end
  end
end
end

The variable dist_parc should be a cell, if I run this as a script ( with the same variable values), it is. If I run the function it ends up being a double. Any idea why?

Could you give us some suggested input?

Do not use path as a variable name, as MATLAB might misinterpret it as the key variable path that MATLAB uses to figure out what functions are available to be called.
