Dear all, I have an array with fractions as elements, which is rendered like this one: http://upload.wikimedia.org/math/f/4/a/f4a5b1f44f4720ce28de1443b3a5b94f.png
There seems to be a solution, adding \\[0.3em] at the end of each line in the array. The code will look like this: \[ M = \begin{bmatrix} \frac{5}{6} & \frac{1}{6} & 0 \\[0.3em] \frac{5}{6} & 0 & \frac{1}{6} \\[0.3em] 0 & \frac{5}{6} & \frac{1}{6} \end{bmatrix} \] It should be rendered like: http://upload.wikimedia.org/math/2/8/9/2898f4774c7df3ad83ad6d31c82c3bf5.png The question is, how can I add the double slash in math environment? Everytime I try to do it, a regular slash is rendered. Thanks in advance. ------------------------------------------------- Julio Rojas jcredbe...@gmail.com
