Please help

Dear Sirs,

I have question.

For example I have 2x2 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.

It's not clear to me what you want the size of the final "array of arrays" to be. 2x2x5? 10x2? Or do you want to generate 5 different 2x2 arrays, perhaps stored in a cell array?

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
