Rank of matrix Rank(a)= According to the principle of elementary row transformation, the original matrix is transformed into a stepped matrix, and the total number of rows minus the number of rows that are all zero, that is, the number of non-zero rows is the rank of the matrix. ...
The rank of a matrix is equal to the number of linearly independent rows (or columns) in it. Hence, it cannot more than its number of rows and columns. For example, if we consider the identity matrix of order 3 × 3, all its rows (or columns) are linearly independent and hence its...

把有向图表想像成单向通行的道路就可以了。 图表能用各种的方法来表示,但一般用在数据结构上的是「邻接行列(adjacency matrix)」和「邻接列表(adjacency list)」。需要注意的是,如果是无向图表,邻接行列 A 就成为了对称行列,而如果是有向图表,A 就会成为不对称行列。

PageRank is highly correlated with citation count (R = 0.905, P < 0.01) and we thus validate the former as a surrogate of literature importance. Furthermore, the algorithm can be run in trivial time on cheap, commodity cluster hardware, lowering the barrier of entry for resource-limited ...
