MATLAB: How to creating matrix h 4×2 with some rules

matrix manipulationreshape matrix

I have some trouble when creating matrix 4×2 with rules like below. the first column are integer and the other column are random number. I already create the syntax below.
for ii = 1:8,
      nilai = mod(ii,2);
  if  nilai == 0
      x(ii) = 0.95 + (1.05-0.95)*x(ii);
  elseif nilai ~= 0
      x(ii) = round(3 + (30-3)*x(ii));
  elseif nilai ~= 0
      x(ii) = 0.01 + (0.055-0.01)*x(ii);
  else
      x(ii) = 1.0 + (1.15-1.0)*x(ii);
  end
 end
x = reshape(x,4,2)';
but the result are
??? Error using ==> reshape
To RESHAPE the number of elements must not change.
anyone can help me with this problem..? any solutions are very welcome..
thank you.

What is the shape of x before you start? It seems that it is probably not an 8-element array, so the reshape fails.
