Issue
I have three arrays x, y, data,
with:
print(x.shape, y.shape, data.shape)
(565, 1215) (565, 1215) (565, 1215)
whereby:
print(x.min(), y.min(), data.min(), x.max(), y.max(), data.max())
-55.530094 33.582264 0.0 55.530094 66.823235 275.67851091467816
How can I select values from 2d array data
where ((x>=-20) & (x<=20) & (y>=35) & (y<=60))
?
I tried the following:
indices = np.where((x>=-20) & (x<=20) & (y>=35) & (y<=60))
print(indices)
(array([ 28, 28, 28, ..., 540, 540, 540], dtype=int64), array([ 35, 36, 37, ..., 671, 672, 673], dtype=int64))
How can I apply this indices to data
?
Solution
Simply data[indices]
Example:
import numpy as np
x = np.random.uniform(0, 100, size=(100, 100))
y = np.random.uniform(0, 100, size=(100, 100))
data = np.random.randint(0, 1000, size=(100, 100))
indices = np.where((x >= -20) & (x <= 20) & (y >= 35) & (y <= 60))
print(data[indices])
