Re: How to use arrays efficiently?

Yes, of course. How blind of me. Here is one more question.
If you change IOUArray to IOArray and add $! in front of the two summations in the previous code, it still works correctly.
But can you do similar trick with Array and accumArray? I have tried to put $! in different places in the first code that I posted but nothing seems to work.

Thanks for help. I did some tests with UArray and it does the trick.
The problem remaining is, how to implement UArray Int (Double, Double, Double)?

Maybe an (UArray (Int,Int) Double) could help, where the second index range is fixed to (0,2).
