本文给出了域上矩阵的Frobenius标准形的一个确定性算法。在同一时间恢复相似变换矩阵。该算法几乎是最优的,需要大约相同数量的字段操作所需的矩阵乘法。先前已知的矩阵乘法的约简是概率性的。
A deterministic algorithm for computing the Frobenius canonical-form of a matrix over a field is described. A similarity transformation-matrix is recovered in the same time. The algorithm is nearly optimal, requiring about the same number of field operations as required for matrix multiplication. Previously-known reductions to matrix multiplication are probabilistic.
