numpy argmax
Notes. 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) >>> a array([[0, 1, 2], [3, 4, 5]]) >>> np.argmax(a) 5 >,numpy.argmax¶. numpy.argmax(a, axis=None, out=None)[source]¶. Returns the indices of the maximum values along an axis. Parameters: a : array_like. Input array. axis : int, optional. By default, the index is into the flattened array, otherwise along the sp

这里应该是拿min/max(更适合处理可迭代对象,可选的参数是key=func)与np.min/np.max(可适合处理numpy.ndarray对象,可选的参数是axis=0或者1)作比较,只不过np.argmin/np.argmax的用法与np.min/np.max相似,这里就不进行更正了。 首先min/max与np.argmin/np.argmax函数的功能不同前者返回值,后者 ... https://blog.csdn.net 详解numpy的argmax - 荷楠仁- 博客园
从最简单的例子出发. 假定现在有一个数组a = [3, 1, 2, 4, 6, 1]现在要算数组a中最大数的索引是多少.这个问题对于刚学编程的同学就能解决.最直接的思路,先假定第0个数最大,然后拿这个和后面的数比,找到大的就更新索引.代码如下 a = [3, 1, 2, 4, 6, 1] maxindex = 0 i = 0 for tmp in a: if tmp > a[maxinde... http://www.cnblogs.com |
