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.
