However the formula for even a \(3 \times 3\) matrix is very long and is not the most efficient way to compute the inverse of a matrix. In Chapter 12 we will develop a technique to compute the inverse of a higher-order matrix, if it exists. WebZero matrix: we denote by 0 the matrix of all zeroes (of relevant size). Inverse: if A is a square matrix, then its inverse A 1 is a matrix of the same size. Not every square matrix has an inverse! (The matrices that have inverses are called invertible.)

It can be proved that the trace of a matrix is the sum of its (complex) eigenvalues (counted with multiplicities). It can also be proved that tr (AB) = tr (BA) for any two matrices A and B. This implies that similar matrices have the same trace. top3b基因

"The trace, tr(A) of a square matrix A is the sum of its diagonal entries. While matrix multiplication is not commutative, the trace of the product of two matrices is independent of the order of the factors: This is immediate from the definition of matrix multiplication: Also, the trace of a matrix is equal to that of its transpose, i.e., " - Properties of square matrix
