Try this::
n = inputdlg('Enter the length of the vector (integer): ');
n = str2double(n);
syms x
x = sym('x',[1 n])
producing (for n = 5):
x =
[x1, x2, x3, x4, x5]
Reference as you would any other vector:
v3 = x(3)
producing:
v3 =
x3
.

My pleasure!
That is exactly what my code example does. The elements of the ‘x’ vector here are symbolic. See the documentation on the sym function for details.
Running:
whos x
after running my code reveals:
Name Size Bytes Class Attributes
x 1x5 8 sym
So it creates a symbolic vector for ‘x’.
