np.unravel_index()函数的正确写法是:numpy.unravel_index(indices, shape, order='C'),官方给的解释这个函数的作用是:“convert a flat index or array of flat indices into a tuple of coordinate arrays”,就是找出shape尺寸数组展平后的第indices个数,在原shape尺寸数组中的位置。 indices:An integer array...

scipy是Python中科学计算程序的核心包; 它用于有效地计算numpy矩阵,来让numpy和scipy协同工作。 在实现一个程序之前,值得检查下所需的数据处理方式是否已经在scipy中存在了。作为非专业程序员,科学家总是喜欢重新发明造轮子,导致了充满漏洞的,未经优化的,很难分享和维护的代码。相反,Scipy程序经过优化和测试,因此应该...
