Below is code demonstrating how to typeset matrices in LaTeX using the array environment. \begin{displaymath} Q = \left( \begin{array}{ccc} q_{11} & q_{12} & q_{13} \\ q_{21} & q_{22} & q_{23} \\ q_{31} & q_{32} & q_{33} \\ \end{array} \right) \end{displaymath} The code generates a three column matrix with the contents of each column centered ({ccc}).

For a recent project one of my research students needed to generate exponentially distributed random numbers in MATLAB. The Statistics Toolbox has a built-in function to do this, but I don’t have a license for this toolbox. Below is the code we wrote. It performs a log transformation to convert a uniformly distributed random number

It is possible, and only slightly awkward, to make LaTex tables with borders around some of the cells and no borders or only partial borders around other cells. Below are two snippets of code showing you how. Each is followed by an image of the table it produces. This code uses two LaTex packages, multirow
