Given two n x n matrices A and B with rational or integral entries, Magma can test whether A is conjugate to B in GLn(Z).
Currently, the implementation is limited to the cases where A, B have finite order or where n=2. This limitation will be removed in future versions.
Tests whether two rational or integral matrices A and B are conjugate in GLn(Z) or SLn(Z). If so, a matrix x such that Ax = B is also returned.
Given a rational or integral matrix A, this function returns its centralizer in GLn(Z). The current implementation is limited to the cases where either A has finite order or A is a 2 x 2 matrix.[Next][Prev] [Right] [Left] [Up] [Index] [Root]
