Using A For Loop To Create Symbolic Variables

Question

I am trying to create a large number of symbolic variables using a for loop, so that I do not have to type each individual variable. Here is my attempt:

for i 1:19
    yi = sym('yi');
end

However, I am getting this error: Unexpected MATLAB expression.

Answer 1

I don't have access to the Symbolic Math Toolbox but see if this helps:

for i=1:19
 eval(sprintf('y%d = sym(''y%d'')', i,i))
end 

Although, I highly recommend against doing it this way.
