Hello, I want to solve a quartic polynomial with complex coefficients.. I tried "polyroots" function but it gives an error "cannot calculate",, Is there a plugin or a function that can solve a polynomial with complex coefficients in SMath? Thanks in advance

Hi,
Here an example solved by using Maxima plugin:

How to put these answers of Maxima plugin inside a vector?

If you have the complex quartic complex vector,
the way to plot is via Lagrange Iterated Product.
From there, your quartic is now a function in native Smath.
You can find roots and more solving demands.

You can use maple() too.
Maple has a fsolve() function.
Which uses floating-point arithmetic.

A little trikiest

Okayy,,,The trick using num2str is so cool..

And thanks overlord, I didnt know about this maple one

Hi. Another way.
