`numpy.ma.core:set_fill_value`

source: build-install/usr/lib/python3.14/site-packages/numpy/ma/core.py :508

Signature

def set_fill_value ( a , fill_value )

Summary

Set the filling value of a, if a is a masked array.

Extended Summary

This function changes the fill value of the masked array a in place. If a is not a masked array, the function returns silently, without doing anything.

Parameters

a : array_like: Input array.
fill_value : dtype: Filling value. A consistency test is performed to make sure the value is compatible with the dtype of a.

Returns

: None: Nothing returned by this function.

Examples

import numpy as np
import numpy.ma as ma
a = np.arange(5)
a
a = ma.masked_where(a < 3, a)
a
ma.set_fill_value(a, -999)
a

Nothing happens if `a` is not a masked array.

a = list(range(5))
a
ma.set_fill_value(a, 100)
a
a = np.arange(5)
a
ma.set_fill_value(a, 100)
a
