Important: The linalg package has been deprecated. Use the superseding packages, LinearAlgebra and VectorCalculus, instead.

- For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.

The fibonacci(n) calling sequence returns the nth fibonacci matrix, $F\left(n\right)$, defined as follows:

Note: Only the first $\dim \left(F\left(n-1\right)+\dim \left(F\left(n-2\right)\right)\right)$ rows and columns are retained.

The command with(linalg,fibonacci) allows the use of the abbreviated form of this command.

$\mathrm{with}\left(\mathrm{linalg}\right)\:$

$\mathrm{fibonacci}\left(3\right)$

$\left[\begin{array}{ccc}1& 1& 1\\ 1& 0& 1\\ 1& 1& 0\end{array}\right]$
