Optimize dense matrix mult for transposed inputs This introduces specialized kernels for dense matrix multiplication involving transposed inputs (t(A)%*%B, A%*%t(B), t(A)%*%t(B)). Previously, these operations required an explicit intermediate transpose step, which caused unnecessary runtime. The new kernels perform the operations in-place or using tiled-transposition, avoiding the full allocation cost. Performance benchmarks on 100x100 dense matrices show significant speedups especially for t(A)%*%B and t(A)%*%t(B) and can be tested with higher dimensions. -- This is an automated message from the Apache Git Service.
