Success. arrayToVector :: FFTWReal r => CArray Int (Complex r) -> V.Vector (Complex r) is the correct type declaration. It seems that I am too eager to assign Double to places where `r` would work, and it's entirely due to an obviously glaring whole in my understanding of type classes. I kind of thought i understood them, but i obviously don't, no I need to go figure that out. I also need to spend time to understand exactly how that type declaration solved the error messages. Thanks very much for your help, I really appreciate it ! Brian
