Hello guys.

I have this problem and I don't know how to start :

Using the implementation of Bairstow method, find the roots of the equation x^3-x^2-x-1=0 with p=-2 q=-1 eps=1 .

Can anyone help me please with the implementation ? Thank you very much.

To start, first study the Bairstow method: https://en.wikipedia.org/wiki/Bairstow%27s_method. After you completely understand the maths behind the method, study the following FEX packages to learn its implementation in MATLAB.

https://www.mathworks.com/matlabcentral/fileexchange/50223-bairstow-s-method-of-finding-all-roots-of-a-polynomial

After you have studied the code in these packages, you will be able to easily write the code for your homework.
