`vector-unfold``f``length``initial-seed``...`procedureThe fundamental vector constructor. Creates a vector whose length is

`length`and iterates across each index k between 0 and`length`, applying`f`at each iteration to the current index and current seeds, in that order, to receive n + 1 values: first, the element to put in the kth slot of the new vector and n new seeds for the next iteration. It is an error for the number of seeds to vary between iterations. Note that the termination condition is different from the`unfold`procedure of SRFI 1.Examples:

(vector-unfold (lambda (i x) (values x (- x 1))) 10 0) ;=> #(0 -1 -2 -3 -4 -5 -6 -7 -8 -9)

Construct a vector of the sequence of integers in the range [0,n).

(vector-unfold values n) ;=> #(0 1 2 ... n-2 n-1)

Copy vector.

(vector-unfold (lambda (i) (vector-ref vector i)) (vector-length vector))
