How do I create an array with unequal increment?

I want to design a program to create an array of numbers. The user can input the maximum and minimum values and the scaling factor.
For example,
max=256,
min=2,
scaling factor=2.
The array will be [2 4 8 16 32 64 128 256].
Is there anyway I can create such array with the max, min and scaling factor as variables? I tried doing it with the following code. However, the x(count) only gives me 1 number instead of storing the answers from the loop.
Is this the right direction to do it? Or is there any other codes to do it in a more efficient way?
Thanks!
xmax=256;
xmin=2;
xfact=2;
count=0;
x=0;
if x<=xmax
count=count+1;
x(count)=x*xfact;
end

Try this:
expspace = @(vmin,vmax,inc) vmin * inc.^(0:( log(vmax/vmin)/log(inc)));
vmin = 2;
vmax = 256;
inc = 2;
v = expspace(vmin, vmax, inc)
v =
2 4 8 16 32 64 128 256
It is also robust to other combinations of input arguments.
