How can i create the below Matrix most elegantly using two for loops.

|1 8  15|
|2 9  16|
|3 10 17|
|4 11 18|
|5 12 19|
|6 13 20|
|7 14 21|

i tried doing:

for i=1:21;
X = i;
for j=1:3 ;
Matrix[] =[X(i) Y(j)];

i asked using 2 for loops.

[Walter Roberson]

for J = 1 : 1
  for K = 1 : 1
    Matrix = reshape(1:21,7,[]);
  end
end

@Shashank Sharma: why do this in two loops? A neater, faster and much more expandable solution is to use Azzi Abdelmalek's original answer. The title of your question is "How can i create the below Matrix most elegantly using two for loops". The most elegant solution is not to use loops, but to use Azzi Abdelmalek's answer.
