The paper deals with the development of the approach to the transformation of sequential algorithms (with certain properties) into vectorized ones, which was suggested earlier by the author. Vectorized algorithms are constructed for linear systems with special-type matrices such as Toeplitz, Hankel, Toeplitz-plus-Hankel, Cauchy and Vandermonde matrices. The vectorized algorithms are used for obtaining new fast algorithms for the Hankel and Toeplitz systems, which require that 5η\ο%\η multiplications and lOnlogjn additions be performed for matrices of order n. In all the algorithms, no other assumption but that of the non-singularity of the leading submatrices is imposed on the coefficient matrix.
