I tried to enter a matrix in this forum and all I get is a big mess when I go to preview the matrix. It seems that the tool decides to get rid of the spaces in the matrix. These spaces are important. For instance if k = the rotation matrix with the first row 0 -1 and the second row 1 0(adsbygoogle = window.adsbygoogle || []).push({});

_ _

| 0 -1 |

k= |_ 1 0 _|

Does someone have a suggestion on a better way to write this?
