Octave Tutorial #15: Solve Polynomial Equations using Octave/Matlab 

Hope this tutorial video is useful for you who would like to learn Matlab and GNU Octave, and please let me know if you have any questions and comments!

Wow. This is a fantastic way to check my homework. Thank you, sir. Great video.

Thanks very much. I tried the problem you gave at the end: >> roots([1 -5 5 5 -6]) ans = 3.0000 -1.0000 2.0000 1.0000 I also got complex roots (for x^2 + 1 = 0): >> roots([1 0 1]) ans = -0 + 1i 0 - 1i

Thanks

very very helpful

Please help 🙏🙏 Suppose there are two simultaneous quadratic equations and we want to calculate the values of it... Then how do we do this in octave?

hello sir, what about x^100 -121 ? how to write it in octave? thanks alot
