The development of software for fast DCT-VIII algorithms for short-length input sequences

This dataset is MATLAB programming code implementing the developed algorithms for DCT-VIII. DCT-VIII stands for Discrete Cosine Transform type eight. This dataset was created in MATLAB version R2023b Update 4 (23.2.0.2428915), 64-bit (win64), November 23, 2025.The research includes basic research. The goal was to develop fast algorithms for the eighth type of discrete cosine transform. To achieve this, matrix patterns described by Aleksandr Cariow in the paper "Strategies for the Synthesis of Fast Algorithms for the Computation of the Matrix-vector Products" [DOI:10.7726/jspta.2014.1001] were used.
