Description
|
|
|
•
|
The call jordan(A) computes and returns the Jordan form J of a matrix A.
|
|
•
|
J has the following structure:  where the ji's are Jordan block matrices. The diagonal entries of these Jordan blocks are the eigenvalues of A (and also of J).
|
|
•
|
If the optional second argument is given, then P will be assigned the transformation matrix corresponding to this Jordan form, that is, the matrix P such that  .
|
|
•
|
The Jordan form is unique up to permutations of the Jordan blocks.
|
|
•
|
The command with(linalg,jordan) allows the use of the abbreviated form of this command.
