No, not really. :cl-array was put in for internal use, and I tried after you posted to comp.lang.lisp (I'm assuming you are allchemist) and it doesn't work. I'll need to clean that up. I think your use of :data is on the right track but you'll have to make your array with c-array:make-ffa if you want to use it in GSL.
In general I think it would be a good idea to be able easily go back and forth between CL and marrays.
1+ (or equivalently (incf *interested-in-this-issue*))
I'm not sure the best way to do that at present and what changes need to be made. I'll have to think about it. Unfortunately I won't be able to get to this for a while.

Hi all!
There is a keyword :cl-array for the gsll:make-marray function. Can I use it to convert native lisp array into marray? I'm trying to do this: (defparameter *m* (make-array '(3 3) :element-type 'single-float :initial-contents '((1.0 2.0 3.0) (4.0 5.0 6.0) (7.0 8.0 9.0)))) (gsll:make-marray 'single-float :dimensions '(3 3) :cl-array *m*) leads to error "Invalid initialization argument: :cl-array". (sbcl, of course) Am I right, using :cl-array in such a way? I have searched for examples with thes key, but found nothing.
Also, if I use :data key instead of :cl-array, it works, but tue resulting marray couldn't be used in common routines, such as matrix multiplication, because it isn't simple-array.
To generalize the problem - Is it possible to convert lisp array to gsll marray without copying data?
Thanks
