how to store all the results in a table with index

hello for exmpl a=length(point);%are already stored in an array for i=1:a-2 for j=i+1:a-1 for k=j+1:a b =point(i,2)+point(j,1)+point(k,1); end end end how to store all the results in a table with 3point ( i(x,y) ,j(x,y),k(x,y))indice??

The code is not readable and I do not understand the question.

I don't understand either. I don't think you need a table, though I applaud you for wanting to use this new (as of R2013b) variable type. I think a regular numerical array would be fine.

Are you trying to create a 3D variable called "b" where the x, y, and z indexes are taken from the "point" array and you just want to set it to 1 or something? Like

numberOfPoints = size(points, 1);
for l=1:numberOfPoints 
  row = points(k,1);
  column = points(k, 2);
  z = points(k,3);
  b(row, column, z) = 1;           
end

That's just a SWAG

Also, be aware that a=length(point) takes the longest dimension. Length() takes the longest dimension when you're using it on a multidimensional array. That's why it's safer to use size() so you know for sure what you're getting.

I'll explain,I have a table that contains 80 points..I have to form triangles of 3 points=>and calculate distances and angles entered each 3 points and then in a table stokes.. that's why I used 3 loop

OK, in that kind of "round robin" type of situation then you would need 3 nested for loops. But we still don't know what your badly-named "b" is. See this:

@bil bbil: Please note, that neither "table" nor "points" is well defined here.

Please start with formatting your code in the question. Thanks.
