I want to write a program that get n from user and solve n equation with n variable. How should I write solve command.
variable: syms V1 , V2 , ... , Vn
equations: eq=[eq1 eq2 ... eqn]
solve(eq(1:end),V1,V2,...,Vn)
My question is about writing n variable at solve command. Thanks.

variant
function out = slveqs(namvar,n,eqs)
%{
namvar - string (e.g. namvar = 'V')
n - double (e.g. n = 2)
eqs - cell array string value(e.g. eqs = {'V1^2-V2 = 4','V1+V2 = 8'})
%}
k = num2cell(sym(namvar,[n,1]));
out = solve(eqs{:},k{:});

clc;
clear all;
n=input("Enter Number of Equations to be formed: ");
syms v [1,n]
for i=1:n
eqn(i) = (v(i)+1)^2+(v(i)-1)^2==20;
disp(eqn(i));
end
S=solve(eqn)
After this u get an array where the values are stored in symbols
