Discussion

SineTransformForwardMatrix_DST2 Discrete Sine Transform (DST-II) matrix Forward scaling: 2/N (no endpoint tweaks). With this choice, the inverse (DST-III) is the plain sine matrix with the HIGHEST-frequency (last) COLUMN halved. If X = SineTransformForwardMatrix_DST2(N) * x, then x = InverseSineTransformMatrix_DST2(N) * X. See also: InverseSineTransformMatrix_DST2
