numpy.ma.flatnotmasked_edges() function find the indices of the first and last unmasked values.
Syntax : numpy.ma.flatnotmasked_edges(arr)
Parameters :
arr : [ array_like] Input 1-D MaskedArray.Return : [ndarray or None] The indices of first and last non-masked value in the array. Returns None if all values are masked.
Code #1 :
# Python program explaining # numpy.ma.flatnotmasked_edges() function # importing numpy as geek # and numpy.ma module as ma import numpy as geek import numpy.ma as ma arr = geek.ma.arange(12) gfg = geek.ma.flatnotmasked_edges(arr) print (gfg) |
Output :
[ 0, 11]
Code #2 :
# Python program explaining # numpy.ma.flatnotmasked_edges() function # importing numpy as geek # and numpy.ma module as ma import numpy as geek import numpy.ma as ma arr = geek.ma.arange(12) arr[:] = geek.ma.masked gfg = geek.ma.flatnotmasked_edges(arr) print (gfg) |
Output :
None
