Use kunpeng optimized eigen
======================

## How to Use
The compilation option **KUNPENG_USE** is used to control whether to use kunpeng optimization,the optimization depends on **kblas** in the Kunpeng math library.

If you want to use this optimization, you need to install the kunpeng math library first, and the minimum version is 2.1.0.

And now the optimization is applicable only to **Kunpeng sve** instruction.

For example enable kunpeng optimization:

```shell
g++ -I./ your_app.cpp -O2 -o your_app -L/usr/local/kml/lib/sve/kblas/nolocking/ -lkblas -fopenmp -DKUNPENG_USE
```
