import numpy as np matrix = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) row_max_indices = np.argmax(matrix, axis=1) print(f"Indices of row-wise maximum values: {row_max_indices}") 4. 使用np.argwhere np.argwhere返回满足条件的元素的坐标(索引)。它返回一个包含坐标的数...
numpy.argwhere()numpy.argwhere()函数返回非零元素的下标,就像上面的 numpy.nonzero()函数一样,但返回的结果是一个简单的n×m numpy数组,其中n是给定数组中非零元素的数量,m是给定数组每个维度的长度。语法如下:numpy.argwhere(arr) Python Copy下面是一个例子:...

min(序列数组, key = lambda i: values[i]) 效果是一样的 进一步: objs = [cls1, cls2, cls3] index_min =min(range(len(objs)), key=lambdai:objs[i].YourNumberProperty) 总结: 善用 min/max 的 key p.s: numpy使用 np.argmin(values) 直接返回 index...

Numpy array transformation 按照@Naga kiran的建议做,然后用原始数组中的值替换上采样数组中的值,怎么样? import numpy as nparr = np.array([4.62236694, 4.62236910, 4.62237128, 4.62237562,])upsamle = np.arange(arr.min(), arr.max()+2.17e-6, step = 2.17e-6)print(f'upsamle = \n{upsamle}'...
