# ros_np_multiarray
Convert between numpy ndarray and ros multiarray message.
## Usage
This is a simple example.
```py
from ros_np_multiarray import ros_np_multiarray as rnm
import numpy as np
print(rnm.to_multiarray_f32(np.array([[[1.0, 2.0], [3.0, 4.0]]], dtype=np.float32)))
```
We get the data converted to 'std_msgs/Float32MultiArray'.
