I Run this code and it works correctly, but I wanna stop the for loop when it gets Empty sym: 0-by-1
for p=0:10
ub= vpasolve(function==0,x,[1000*p,1000*(p+1)])
end

"vpasolve" returns numerical values. Its output "ub" cannot be a sym variable. If you use "solve", you can use "isempty" and "break" for your pourpose.
syms x
for k = 1:2
out = solve(x^k + 1 == 0, x)
if isempty(out) == 1
disp('break')
break;
end
disp('in loop')
end

This is not quite correct. vpasolve() returns symbolic values that represent numeric values. They are sym, and when no solution is found then the empty sym can be returned.
Also there is no need to compare isempty() to 1: you can just test if isempty(out)
