Faddeev–LeVerrier algorithm
The Faddeev-Leverrier algorithm is like a magic trick that helps people find out something special about a matrix.
Imagine a very long list of numbers written in a rectangular shape, just like a Lego piece. These numbers are called the matrix. The matrix can be used to solve many math problems.
Now, imagine that you want to know something special about this matrix, like how many Lego pieces can be made out of it or how strong it is. To find out, you use the Faddeev-Leverrier algorithm.
The first thing you need to do is to mix all the numbers in the matrix and write them in a new matrix. Then, you subtract a chosen number from the top left corner of the new matrix. This chosen number can be any number you want, as long as it is not zero.
Next, you repeat the same process, but this time using the new matrix you just created. You mix all the numbers in the new matrix and write them in another new matrix. Then, you subtract the chosen number from the top left corner of the new matrix again.
You repeat this process many times, each time creating a new matrix and subtracting the chosen number from the top left corner. Finally, you end up with a matrix that has some special numbers in it. These special numbers can tell you something about the original matrix.
This algorithm may seem very complicated, but it is actually very simple if you follow the steps carefully. It is like a fun puzzle that helps you unlock the secrets of a matrix.
