solve can solve inequalities to find a solution that satisfies the inequalities.
Solve the following inequalities. Set ReturnConditions to true to return any parameters in the solution and conditions on the solution.
syms x y
S = solve(x^2 + y^2 + x*y < 1, x > 0, y > 0,...
[x, y], 'ReturnConditions', true);
solx = S.x
soly = S.y
params = S.parameters
conditions = S.conditions
