Hello,
I am trying to solve a determinant of 4x4 matrix and getting answer equal to zero. Can anyone help me to find the other non-zero values for this equation. (means other periodic values for this function or other way to get non-zero approximations). I 'll be very thankfull if anyone can take a look at the attached file.

Which solution do you wish to find?
F = matlabFunction(det(X));
fplot(F,[0 .1])

It appears there might be 2 or 3 solutions. Or perhaps 2 or 3 trillion of them. Or why stop at any finite number?
vpasolve(det(X),.06)
ans =
0.01931385561569357106926176060344
vpasolve(det(X),.07)
ans =
0.069995054245726529446727985175491

Thank you so much for your precious time and support. Infact I was looking for the first non-zero solution for the given function. By using solve(x), I got the answer equal to zero; but now by using vpasolve(X) I am able to get the required answer.
