Example #1

            var src      = Create8x8RandomFloatData(-200, 200, seed);

            srcBlock.LoadFrom(src);

            var destBlock = new Block8x8F();

            var expectedDest = new MutableSpan <float>(64);

            DCT.FDCT8x4_LeftPart(ref srcBlock, ref destBlock);

            var actualDest = new MutableSpan <float>(64);
