I will run some benchmarks.
EDIT: runs a bit slower than Expr(), 113fps vs 143 fps, I used 16-bit clip in Expr() though (internally works in float)

Thanks for the feedback, can you explain what transposing and all those terms mean to explain your use case please? The order was chosen based on how the Adobe suite typically presents it, but it would be no problem to just add an alternate function name for a different order if desired, or one that just works without offsets.
Does Expr allow to do matrix transforms like this? It's actually one of the first things I looked into when I tried doing this but I couldn't figure it out. I know how to apply operations on individual pixels in Expr but I don't know how to take the other channels into account in the calculation.
