numpy.minimum() function is used to find the element-wise minimum of array elements.
It compare two arrays and returns a new array containing the element-wise minima. If one of the elements being compared is a NaN, then that element is returned. If both elements are NaNs then the first is returned.
Syntax : numpy.minimum(arr1, arr2, /, out=None, *, where=True, casting=’same_kind’, order=’K’, dtype=None, ufunc ‘minimum’)
Parameters :
arr1 : [array_like] Input array.
arr2 : [array_like] Input array.
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 you 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] Result.
The minimum of arr1 and arr2, element-wise. This is a scalar if both arr1 and arr2 are scalars.
Code #1 : Working
# Python program explaining# minimum() function import numpy as geekin_num1 = 10in_num2 = 21 print ("Input number1 : ", in_num1)print ("Input number2 : ", in_num2) out_num = geek.minimum(in_num1, in_num2) print ("minimum of 10 and 21 : ", out_num) |
Output :
Input number1 : 10 Input number2 : 21 minimum of 10 and 21 : 10
Code #2 :
# Python program explaining# minimum() function import numpy as geek in_arr1 = [2, 8, 125]in_arr2 = [3, 3, 15] print ("Input array1 : ", in_arr1) print ("Input array2 : ", in_arr2) out_arr = geek.minimum(in_arr1, in_arr2) print ("Output array after selecting minimum: ", out_arr) |
Output :
Input array1 : [2, 8, 125] Input array2 : [3, 3, 15] Output array after selecting minimum: [ 2 3 15]
Code #3 :
# Python program explaining# minimum() function import numpy as geek in_arr1 = [geek.nan, 0, geek.nan]in_arr2 = [geek.nan, geek.nan, 0] print ("Input array1 : ", in_arr1) print ("Input array2 : ", in_arr2) out_arr = geek.minimum(in_arr1, in_arr2) print ("Output array after selecting minimum: ", out_arr) |
Output :
Input array1 : [nan, 0, nan] Input array2 : [nan, nan, 0] Output array after selecting minimum: [ nan nan nan]
