numpy.ma.MaskedArray class
is a subclass of ndarray designed to manipulate numerical arrays with missing data. With the help of Numpy MaskedArray.__iadd__ we can add a particular value that is provided as a parameter in the MaskedArray.__iadd__() method. Value will be added to each and every element in a numpy array.
Syntax: numpy.MaskedArray.__iadd__(other)
Return: Add other to self in-place.
Example #1 :
In this example we can see that each and every element in an array is added with the value given as a parameter in method MaskedArray.__iadd__(). Remember one thing it wouldn’t work for double type values.
import numpy as np
gfg = np.ma.array([ 1 , 2 , 3 , 4.7 , 5.2 ])
print (gfg.__iadd__( 5 ))
|
Output:
[ 6. 7. 8. 9.7 10.2]
Example #2:
import numpy as np
gfg = np.ma.array([[ 1 , 2 , 3 , 4 , 5 ],
[ 6 , 5 , 4 , 3 , 2 ]])
print (gfg.__iadd__( 5 ))
|
Output:
[[ 6 7 8 9 10]
[11 10 9 8 7]]
