matrix for Ternary ABC points

hello,

i need to generate a matrix with an interval of 0.05 for a ternary system, like;

[0     0     100     -------------> sum of each row must be 100
 0     0.05  99.95
 .     .     .
 .     .     .
 0.05  0     99.95
 0.05  0.05  99.9
 .     .     .
 .     .     .
 100   0     0]

help would be greatly appreciated.

Answer 1

[Andrei Bobrov]

so?

a = (0:.05:100)';
[x y] = ndgrid(a);
out = [y(:) x(:) flipud(x(:))];

sorry, i forgot to type that sum of data in each rows must be 100.

Answer 2

[M]

i just modified Mr.Bobrov's answer in order to obtain the sum of each row equal to 100;

a = (0:0.05:100)';
  [x y] = ndgrid(a);
  out = [y(:) x(:) flipud(x(:))];
  out(:,3)=(100-(out(:,1)+out(:,2)));
  [badrows,c]=find(out<0);
  newOut = out(setdiff(1:size(out,1),badrows),:);
