symmin = @(x) feval(symengine, 'min',feval(symengine,'op',x))

Why are you trying to use feval on the symengine object to take the minimum of your symbolic input? Why not just call min directly on the symbolic object(s)?
two = sym(2);
three = sym(3);
z = min(two, three)
y = [two three two two three];
z2 = min(y)
