I am trying to solve an inequlaity using feval and the function return the limits in variable sym. May I know how to access the limits of values in sym?
syms b
a = 1;
feval(symengine, 'solve', (1-sqrt(5))*a^2 < b < (1+sqrt(5))*a^2)

Not sure why feval is used. Just using solve with ReturnConditions solves for the range of b that satisfies both inequalities.
syms b
a = 1;
eq1 = (1-sqrt(5))*a^2 < b;
eq2 = b < (1+sqrt(5))*a^2;
sol = solve([eq1;eq2],b,'ReturnConditions',true)
sol = struct with fields:
b: x parameters: x conditions: -347922205179541/281474976710656 < x & x < 910872158600853/281474976710656
