Numpy MaskedArray.masked_greater () Function | python

NumPy | Python Methods and Functions

numpy.MaskedArray.masked_greater() is used to mask the array, numpy.MaskedArray.masked_greater() which is greater than the specified value. This function is a shortcut to masked_where with the condition = (arr & gt; value).

Syntax: numpy.ma.masked_greater (arr, value, copy = True)

Parameters:
arr: [ ndarray] Input array which we want to mask.
value: [int] It is used to mask the array element which are & gt; value.
copy: [bool] If True (default) make a copy of arr in the result. If False modify arr in place and return a view.

Return: [MaskedArray] The resultant array after masking.

Code # 1:

# Python program explaining
# numpy. MaskedArray.masked_greater () method

 
# import numy as a geek
# and the numpy.ma module as ma

import numpy as geek

import numpy.ma as ma

 
# create input array

in_arr = geek.array ([ 1 , 2 , 3 , - 1 , 2 ])

print ( "Input array:" , in_arr)

 
# applying MaskedArray.masked_greater methods
# to enter an array, where value & gt; 2

mask_arr = ma.masked_greater ( in_arr, 2 )

print ( "Masked array:" , mask_arr)

Output:

 Input array: [1 2 3 -1 2 ] Masked array: [1 2 - -1 2] 

Code # 2:

# Python program explaining
# numpy.MaskedArray.masked_greater () method

  
# import numy as geek
# and numpy.ma module as ma

import numpy as g eek

import numpy.ma as ma

 
# create input array

in_arr = geek.array ([ 5e8 , 3e - 5 , - 45.0 , 4e4 , 5e2 ])

print ( "Input array:" , in_arr)

 
# applying MaskedArray.masked_greater methods
# to enter an array, where value & gt; 5e2

mask_arr = ma.masked_greater ( in_arr, 5e2 )

print ( "Masked array:" , mask_arr)

Output:

 Input array: [5.0e + 08 3.0e -05 -4.5e + 01 4.0e + 04 5.0e + 02] Masked array: [- 3e-05 -45.0 - 500.0]
