matrices

Dear Sirs,
I have question.
For example I have 2×2 array A = [1,10;20,30].
Now I want to make array of arrays changing the first position.
How to write function if I want to get this array:
[1,10;20,30]
[2,10;20,30]
[3,10;20,30]
[4,10;20,30]
[5,10;20,30]
So the point is I want to change just A(1,1) (1,2,3,4,5).
Thank you very much in advanced.

Best Answer

A = [1,10; 20,30];
for i = 0:4
  B = A + [i,0; 0,0];
  disp(B);
end
or
A = [1,10; 20,30];
a11 = A(1, 1);
for i = 0:4
  A(1) = a11 + i;
  disp(A);
end
