The RREF method is the most flexible for nonsingular matrices.įor the inplaceRET method, B should never be specified, as the output replaces A. The RET and inplaceRET methods are the most efficient for very large problems. The LU and inplaceLU methods are the most efficient for small to moderate sized problems. Transform to A, replacing A with the inverse or adjoint. Obtain inverse or adjoint through application of a row echelon Obtain inverse or adjoint through application of row reduction Obtain inverse or adjoint via LU decomposition destroying the Obtain inverse or adjoint via LU decomposition. The default method for the inverse is LU, while the default method for the adjoint is RET, and these can be changed by specification of meth. In this case the command will return NULL. If B is specified, it must have dimensions and datatype identical to A, and will contain the inverse or adjoint on successful completion. If det is specified, it is assigned the value of the determinant on successful completion. The Inverse and Adjoint functions compute the inverse and adjoint, respectively, of a square mod m Matrix. (optional) method to use for computing Inverse or Adjoint (optional) Matrix to use for output Inverse or Adjoint (optional) name to use for output determinant Compute the Inverse of a square mod m MatrixĬompute the Adjoint of a square mod m Matrix
