Continuing former investigations by the authors (see the references) the present paper contains metric results on the distribution modulo 1 of the powers of special kinds of real matrices A, namely of (2×2)- and (3×3)-triangle matrices, symmetric (2×2)-matrices and so-called "cosymmetric" (2×2)-matrices (i. e. matrices, symmetric with respect to the secondary diagonal). For almost all such matrices A (in the sense of the Lebesgue measure in ℝ³ resp. ℝ⁶) possessing no eigenvalue of modulus smaller than 1 the inequality {Mathematical expression} is proved as an estimate for the discrepancy of the sequence (A^s(n)) where (s(n))_n^=1/∞ is an arbitrary fixed strictly increasing sequence of positive integers and d is the dimension of the appropriate space ℝ^d (d=3 or 6).
