I have a function that I call but I would prefer the output I get to look more like a vector.

The code is a function calling on another function which computes a sequence of x-values.

 function [] = MatOb()
  x_values = MatOb1(2,2,50);
  x = [x_values];
  s = 'X values:'
  disp(x)
 end
 function [x_values] = MatOb1(a, x, N)
    x_values(1) = x;
    for n = 2:N
        x_values(n) = a*sin(x_values(n-1));
    end
end

The output I get is on the form:

 Columns 1 through 11
    2.0000    1.8186    1.9389    1.8660    1.9135    1.8837    1.9029    1.8907    1.8985    1.8936    1.8967
Columns 12 through 22
    1.8947    1.8960    1.8952    1.8957    1.8954    1.8956    1.8954    1.8955    1.8955    1.8955    1.8955

Is there a way to get the output in a way where it looks more like a vector,

x = [x1,x2,...,xN]? or x = [x1 x2 .... xN]

If I get it right your function MatOb just prints x_values in the standard output. I fail to see the need of introducing one further variable "x". Anyway, if this is just a matter of standard output, you can use fprintf instead of disp

fprintf('x = [%s]\n',sprintf('%1.3f ',x));

As I say, you can do this by using x_values in place of x.

Take a look at the documentation of fprintf and sprintf to get the hang of it.
