摘要：

The numerical algorithms for solving equations of the type AX + X (T) B = C or AX + X*B = C that were earlier proposed by the authors are now modified for the situations where these equations can be regarded as self-adjoint ones. The economy in computational time and work achieved through these modifications is illustrated by numerical results.
