# 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'.

```
