What is the easier way of listing several symbolic variables?

is there a way to list symbolic variables without having to type each one of them? I mean, sometimes I am dealing with several variables, say x1,x2,....,x20; so what would be the 'easiest' way of writing them?

Would

syms x1... x20

work ? (or something similar) ?

Answer 1

[Azzi Abdelmalek]

for k=1:20;
  syms(sprintf('x%d',k));
end

Answer 2

[Sean de Wolski]

for ii = 1:20; 
  syms(['x' num2str(ii)]);
end

But more importantly, can you represent it as one 1x20 vector instead?

Thanks! Not really...

could you enlighten me on how to do this?

[Sean de Wolski]

x = sym(zeros(1,20))

Now fill them in with whatever. E.g.:

x(3) = sym('d')

It's just a thought, there might not be a way around it. Basically we're trying to get away from this, though it is terribly convenient (and sometimes necessary) with symbolic variables.
