Hi, I'm having a difficult time trying to create two columns of data (or three or four etc.) in a float vector. A list works fine, but the vector gives an error that the data is a pair but should be a real. I could use make-env for this probably, but seems like I should be able to get the vector to cooperate. I'm wondering what I'm misunderstanding or if there's a better way to think of this such as individual vectors then zip them together? Thanks, Jim
;float vector XXX (let* ((fsize 10) (im (make-float-vector fsize)) (x 1) (y 1.0) ) (do ((k 0 (+ k 1))) ((>= k fsize)) (set! (im k) (cons x y)) ;XXX is a pair but should be a real? ;(float-vector-set! im k (cons x y)) (format #t "~% ~A ~A" k (im k) ) (set! x (1+ x)) (set! y (1+ y)) )) ;list OK (let* ((fsize 10) (mylist (make-list fsize)) (x 1) (y 1.0) ) (do ((k 0 (+ k 1))) ((>= k fsize)) (set! (list-ref mylist k) (cons x y)) (format #t "~% ~A ~A" k (list-ref mylist k)) (set! x (1+ x)) (set! y (1+ y)) ))
