Witryna10 mar 2024 · In mathematics, a logarithm of a matrix is another matrix such that the matrix exponential of the latter matrix equals the original matrix. It is thus a … In mathematics, a logarithm of a matrix is another matrix such that the matrix exponential of the latter matrix equals the original matrix. It is thus a generalization of the scalar logarithm and in some sense an inverse function of the matrix exponential. Not all matrices have a logarithm and … Zobacz więcej The exponential of a matrix A is defined by $${\displaystyle e^{A}\equiv \sum _{n=0}^{\infty }{\frac {A^{n}}{n!}}}$$. Given a matrix B, another matrix A is said to be a matrix logarithm of B if e = B. Because the … Zobacz więcej The rotations in the plane give a simple example.
