numpy.ma.masked_all() function | Python (original) (raw)

Last Updated : 05 May, 2020

numpy.ma.masked_all() function return an empty masked array of the given shape and dtype, where all the data are masked.

Syntax : numpy.ma.masked_all(shape, dtype)

Parameter :
shape : [tuple] Shape of the required MaskedArray.
dtype : [dtype, optional] Data type of the output.

Return : [MaskedArray] A masked array with all data masked.

Code #1 :

import numpy as geek

import numpy.ma as ma

gfg = ma.masked_all(( 4 , 4 ))

print (gfg)

Output :

[[-- -- -- --] [-- -- -- --] [-- -- -- --] [-- -- -- --]]

Code #2 :

import numpy as geek

import numpy.ma as ma

gfg = ma.masked_all(( 3 , 3 ), dtype = geek.int32)

print (gfg)

Output :

[[-- -- --] [-- -- --] [-- -- --]]
