Np.trace method gives the sum of

WebPython numpy sum function calculates the sum of values in an array. arr1.sum () arr2.sum () arr3.sum () This Python numpy sum function allows you to use an optional argument called an axis. This Python numpy Aggregate Function helps to calculate the sum of a given axis. For example, axis = 0 returns the sum of each column in an Numpy array. Web用法: numpy. trace (a, offset=0, axis1=0, axis2=1, dtype=None, out=None) 返回沿数组对角线的总和。 如果 a 是二维的，则返回其对角线与给定偏移量的总和，即所有 i 的元素 a [i,i+offset] 的总和。 如果 a 具有两个以上的维度，则由 axis1 和 axis2 指定的轴用于确定返回其轨迹的二维子数组。 结果数组的形状与移除了axis1和axis2的a的形状相同。 参数 ： …
