b=find(a==2); 那么得到的b是假设将矩阵铺开成一维向量然后返回查找的位置的,并且是以列优先进行铺开。 在python中,我们使用相同的查找功能是使用where函数,首先加载numpy库,然后调用 import numpy as np b = np.array([[1, 2, 5], [2, 8, 9], [3, 9, 6], [0, 5, 2]]) ...
和find相比,whereis查找的速度非常快,这是因为linux系统会将 系统内的所有文件都记录在一个数据库文件中,当使用whereis和下面即将介绍的locate时,会从数据库中查找数据,而不是像find命令那样,通 过遍历硬盘来查找,效率自然会很高。 但是该数据库文件并不是实时更新,默认情况下时一星期更新一次,因此,我们在用where...
