# result.shape形状的矩阵，第result.argmax()个元素的展开的坐标，第一个参数是一种整数数组，其元素是维度数组dims的扁平版本的索引。
# 例子：
# Consider a (6,7,8) shape array, what is the index (x,y,z) of the 100th element ?
# >>> print np.unravel_index(100,(6,7,8))
# (1, 5, 4)
# 解释：
# 给定一个矩阵，shape=（6,7,8），即3维的矩阵，求第n个元素的下标是什么？矩阵各维的下标从0开始
# 如果indices参数是一个标量，那么返回的是一个向量，维数=矩阵的维数，向量的值其实就是在矩阵中对应的下标。如6*7*8*9的矩阵，
# 1621/(7*8*9)=3，(1621-3*7*8*9)/(8*9)=1，(1621-3*7*8*9-1*8*9)/9=4，(1621-3*7*8*9-1*8*9-4*9)=1。
# 所以返回的向量为array(3,1,4,1)
# 如果indices参数是一个向量的，那么通过该向量中值求出对应的下标。下标的个数就是矩阵的维数，每一维下标组成一个向量，
# 所以返回的向量的个数=矩阵维数。如7*6的矩阵，第22个元素是 3*6+4，所以对应的下标是(3,4)，那么返回的值是 array([3]),array([4]
