| 1 | Chinese literature dating from as early as 650 BC tells the legend of Lo Shu |
|---|
| 2 | or "scroll of the river Lo". In ancient China there was a huge flood. The great |
|---|
| 3 | king Yu tried to channel the water out to sea where then emerged from the water |

| 4 | a turtle with a curious figure/pattern on its shell; circular dots of numbers |
|---|
| 5 | which were arranged in a three by three grid pattern such that the sum of the |
|---|
| 6 | numbers in each row, column and diagonal was the same: 15, which is also the |
|---|
| 7 | number of days in each of the 24 cycles of the Chinese solar year. |

| 13 | An experimental linear algebra library for computer vision. |

| 14 | Includes python bindings and a set of scripts for processing and viewing PCA |

| 15 | calculations. |

| 16 | |

| 17 | The code contains a few dependancies on OpenCV, but only in the image processing |
|---|
| 18 | domain. I'm wary of OpenCV after problems with the code on different |
|---|
| 19 | architectures. |

| 20 | |

| 21 | It's not currenly optimised, but simd code is planned for the matrix |
|---|
| 22 | calculations. |
