170 Appendix C: Wolfram alpha matrix operations

Wolfram alpha carries out some matrix operations using Mathematika.

\{\{1,2\},\{3,4\}\}

This inputs the matrix

\begin{bmatrix}1&2\\ 3&4\end{bmatrix}

then

{\hbox{MatrixExp}}\Bigl{[}\begin{pmatrix}1&2\\ 3&4\end{pmatrix}\Bigr{]}

computes the matrix exponential. Likewise, there is a matrix inverse calculator, a determinant calculator and so on.
