Let P=[[1,0,0],[4,1,0],[16,4,1]]and I be the identity matrix of order 3. If Q = [q()ij ] is a matrix, such that P^(50)-Q=I, then (q(31)+q(32))/q(21) equals
1.3 Powers of Matrices Definition 1.10 (The identity matrix). The n× n matrix I = [δij], defined by δij = 1 if i = j, δij = 0 if i≠ j, is called the n× n identity matrix of order n. In other words, the columns of the identity matrix of order n are the vectors ...

An identity matrix is always an square matrix: As seen in equations 1 and 2, the order of an identity matrix is always n, which refers to the dimensions nxn (meaning there is always the same amount of rows and columns in the matrix). ...
scipy中的稀疏矩阵coo_matrix,csr_matrix,csc_matrix coo_matrix COO优点: 1:容易构造,比较容易转换成其他的稀疏矩阵存储格式(CSR等) 2:写程序可以将libsvm格式的数据转换成COO比较容易,应该是充当libsvm与其他稀疏矩阵存储格式转换的媒介。 3:支持相同的(row,col)坐标上存放多个值。 COO缺点: 1:构建完成后不...
