Find the solution of algebraic equation of the form
an*x^n + a(n-1)*x^(n-1) + (an-2)*x^(n-2)+...... a2*x^2 + a1*x^1 + a0 = 0;
Input to the function is of the form : [an an-1 an-2 .....a2 a1 a0] :coef vector
eg: equation x^5-5=2 -> Input = [1 0 0 0 0 -5]

why it showing the error
"Error: Could not check out Symbolic Math Toolbox license."

Solution set note: i' is -i. More explicit method would be ; usage or rot90. There is another way, which I don't recall to transpose an imaginary array without creating complex conjugates.

i.'

The author should make some change: either the spec or the test cases are flawed, the order of the solution should not matter.

i' = -i
i.' = -i

.' is transpose
' is transpose and then complex conjugate
