I am attempting to add a number of symbolic variables dynamically for a script.
The script will get an input from the user about how many joints they are inputting in for some robotic manipulation calculations. Based on this I would like to insert a number of symbolic variables (equal to the amount specified at the initial input).
Is there a way to do this that isn't creating a bunch of variables in storage like:
syms v1 v2 v3 v4 v5 v6 v7 v8 v9 v9 %...
variables = [v1 v2 v3 v4 v5 v6 v7 v8 v9] %...
numvars = input('How many joints would you like to enter: ');
for i=1:numvars
%Do something
end

numvars = 5; % for example
V = sym('V',[1 numvars])
V =

After further research and help from a friend, here is the answer:
numVars = input('Enter how many joints: ');
variables = sym(zeros(1,numVars));
for i=1:numVars
variables(i) = sym("V"+ num2str(i));
end
disp(variables);
