numpy.fmax() function is used to compute element-wise maximum of array elements. This function compare two arrays and returns a new array containing the element-wise maxima.
If one of the elements being compared is a NaN, then the non-nan element is returned. If both elements are NaNs then the first is returned.
Syntax : numpy.fmax(arr1, arr2, /, out=None, *, where=True, casting=’same_kind’, order=’K’, dtype=None, ufunc ‘fmax’)
Parameters :
arr1 : [array_like] The array holding the elements to be compared.
arr2 : [array_like] The array holding the elements to be compared.
out : [ndarray, optional] A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned.
**kwargs : Allows to pass keyword variable length of argument to a function. It is used when we want to handle named argument in a function.
where : [array_like, optional] True value means to calculate the universal functions(ufunc) at that position, False value means to leave the value in the output alone.Return : [ndarray or scalar] The maximum of arr1 and arr2, element-wise. Returns scalar if both arr1 and arr2 are scalars.
Code #1 : Working
# Python program explaining # fmax() function   import numpy as geek in_num1 = 10in_num2 = 11  print ("Input number1 : ", in_num1) print ("Input number2 : ", in_num2)     out_num = geek.fmax(in_num1, in_num2) print ("maximum of 10 and 11 : ", out_num) |
Output :
Input number1 : 10 Input number2 : 11 maximum of 10 and 11 : 11

Code #2 :
# Python program explaining # fmax() function   import numpy as geek   in_arr1 = [2, 8, 125, geek.nan] in_arr2 = [geek.nan, 3, 115, geek.nan]    print ("Input array1 : ", in_arr1) print ("Input array2 : ", in_arr2)     out_arr = geek.fmax(in_arr1, in_arr2) print ("Output array : ", out_arr) |
Output :
Input array1 : [2, 8, 125, nan] Input array2 : [nan, 3, 115, nan] Output array : [ 2. 8. 125. nan]

Code #3 :
# Python program explaining # fmax() function   import numpy as geek   in_arr1 = [2, 8, 125] in_arr2 = [3, 3, 115]       print ("Input array1 : ", in_arr1) print ("Input array2 : ", in_arr2)     out_arr = geek.fmax(in_arr1, in_arr2) print ("Output array: ", out_arr) |
Output :
Input array1 : [2, 8, 125] Input array2 : [3, 3, 115] Output array: [ 3 8 125]
