Hi
I have never used matlab and have no experience in coding either.
I am trying to get eigen values of following matrix [a11,a12;a21,a22] =A=[1-((2?ab(1+2cb)(1+cb)(2b(1+gb)+d(1+2gb))/(4b^2(1+cb)(1+gb)-d^2(1+2cb)(1+2gb))),2ad(1+2cb)^2((2b(1+gb)+d(1+2gb))/(4b^2(1+cb)(1+gb)-d^2(1+2cb)(1+2gb)));d(1+2gb)/(2b(1+gb)),0]

i tried in two different ways but couln't generate the results

syms A B p r s t
A=[1-((2?ab(1+2cb)(1+cb)(2b(1+gb)+d(1+2gb))/(4b^2(1+cb)(1+gb)-d^2(1+2cb)(1+2gb))),2ad(1+2cb)^2((2b(1+gb)+d(1+2gb))/(4b^2(1+cb)(1+gb)-d^2(1+2cb)(1+2gb)));d(1+2gb)/(2b(1+gb)),0]
B=eig(A)

syms x a b c
f = a + b*x + c*x^2
coefficients = [2 -1 3]
result = roots(coefficients)

Please help. Thanks
