Example 2: Max & Min of Columns in NumPy ArrayExample 2 shows how to find the max and min values of a NumPy array by columns.For this task, we have to set the axis argument to be equal to 0:print(np.max(my_array, axis = 0)) # Get max of array columns # [4 5 6]...
问为numpy数组的特定列设置maxEN一、NumPy简介 NumPy是针对多维数组（Ndarray）的一个科学计算（各种运算...
如下图，使用x == np.max(x) 获得一个掩模矩阵，然后使用where方法即可返回最大值对应的行和列。
importnumpyasnp# 创建一个数组array=np.array([1,2,3,4,5,6,7,8,9])print("Array:",array)# 使用where找出大于5的元素的索引indices_greater_than_5=np.where(array>5)print("Indices greater than 5:",indices_greater_than_5)# 在这些元素中找出最大值的索引index_of_max_in_filtered=np.argmax...
for tmp in a: if tmp > a[maxindex]: maxindex = i i += 1 print(maxindex) 这个问题虽然简单.但是可以帮助我们理解argmax. 解释 还是从一维数组出发.看下面的例子. import numpyasnp a = np.array([3,1,2,4,6,1])print(np.argmax(a)) ...
arr=np.array([1,3,2,7,4])index_of_max=np.argmax(arr)print("Index of max value:",index_of_max)# 输出结果应为3 Python Copy Output: 示例代码2:二维数组默认轴 importnumpyasnp arr=np.array([[1,3,5],[4,2,6]])index_of_max=np.argmax(arr)print("Index of max value in flattened...

The Numpy array is essentially a grid-like data structure that stores numeric data. Locations in a Numpy array have an “index” The next thing you need to know is that every location in a Numpy array has a position. It gets a little more complicated for 2D arrays, so let’s keep thi...
In case of multiple occurrences of the maximum values, the indices corresponding to the first occurrence are returned. Examples >>>a=np.arange(6).reshape(2,3)>>>aarray([[0, 1, 2],[3, 4, 5]])>>>np.argmax(a)5>>>np.argmax(a,axis=0)array([1, 1, 1])>>>np.argmax(a,axi...
