Hi Haskellers, I have been playing with the Repa functions and trying the Repa-examples. In order to gain experience with the Repa functions I have written some small linear algebra utilities and import this module to a bigger project. In the beginning of my project I used the mmultP function from the repa-examples to calculate a big matrix, therefore I have and array of type:
arr :: Monad m => m (Array U DIM2 Double) Then I carried this array in a lot of functions which become Monadic function and then it is necessary to introduce the monadic machinery for manipulating this functions . The Question is then if there is the possibility to work with a pure function in place of the monadic version? There is something like a runRepa function? runRepa :: Monad m => m (Array U DIM2 Double) - > Array U DIM2 Double or could I used the unsafePerformIO function ? or the evaluation of the parallel arrays must be postponed until the Repa.Array is called in the main function? Thanks in Advance, Felipe.
