Numpy MaskedArray.minimum_fill_value()函数| Python

numpy.MaskedArray.minimum_fill_value()函数用于返回对象的 dtype 可以表示的最大值。

代码#1:

# Python program explaining
# numpy.MaskedArray.minimum_fill_value() method 
    
# importing numpy as geek  
# and numpy.ma module as ma 
import numpy as geek 
import numpy.ma as ma 
    
# creating input array  
in_arr = geek.array([1,  3,  5, -3], dtype ='float')
print ("Input array : ", in_arr) 
    
# Now we are creating a masked array. 
# by making  entry as invalid.  
mask_arr = ma.masked_array(in_arr, mask =[1, 0, 0, 0]) 
print ("Masked array : ", mask_arr) 
    
# applying MaskedArray.minimum_fill_value    
# methods to masked array
out_val = ma.minimum_fill_value(mask_arr) 
print ("Maximum filled value : ", out_val) 
输出:
Input array :  [ 1.  3.  5. -3.]
Masked array :  [-- 3.0 5.0 -3.0]
Maximum filled value :  inf

代码#2:

# Python program explaining
# numpy.MaskedArray.minimum_fill_value() method 
    
# importing numpy as geek  
# and numpy.ma module as ma 
import numpy as geek 
import numpy.ma as ma 
    
# creating input array  
in_arr = geek.array([[1, 2], [ 3, -1], [ 5, -3]], dtype ='int')
print ("Input array : ", in_arr) 
    
# Now we are creating a masked array. 
# by making  entry as invalid.  
mask_arr = ma.masked_array(in_arr, mask =[[1, 0], [ 1, 0], [ 0, 0]]) 
print ("Masked array : ", mask_arr) 
    
# applying MaskedArray.minimum_fill_value    
# methods to masked array
out_val = ma.minimum_fill_value(mask_arr) 
print ("Maximum filled value : ", out_val) 
输出:
Input array :  [[ 1  2]
 [ 3 -1]
 [ 5 -3]]
Masked array :  [[-- 2]
 [-- -1]
 [5 -3]]
Maximum filled value :  2147483647
