## Test data
|
||
|
|
|
||
|
|
```python
|
||
|
|
import numpy as np
|
||
|
|
import matplotlib.pyplot as plt
|
||
|
|
|
||
|
|
axis = np.arange(-100, 101) / 100.0
|
||
|
|
|
||
|
|
x = axis[:, np.newaxis, np.newaxis].copy()
|
||
|
|
y = axis[np.newaxis, :, np.newaxis].copy()
|
||
|
|
z = axis[np.newaxis, np.newaxis, :].copy()
|
||
|
|
|
||
|
|
r = np.sqrt(x**2 + y**2 + z**2)
|
||
|
|
|
||
|
|
mask_0 = r > 0.75
|
||
|
|
r = 1.0 / (r + 1.0)
|
||
|
|
r[mask_0] = 0
|
||
|
|
|
||
|
|
plt.imshow(r[100, :, :], cmap="hot")
|
||
|
|
plt.colorbar()
|
||
|
|
plt.title("Cut through center of x-axis")
|
||
|
|
plt.show()
|
