- Scheme Procedure:
**make-vector***size [fill]* Create and return a vector of size

`size`, optionally filling it with`fill`. The default value of`fill`is unspecified.(make-vector 5 3) ⇒ #(3 3 3 3 3)

- Scheme Procedure:
**vector***x …* Create and return a vector whose elements are

`x`....(vector 0 1 2 3 4) ⇒ #(0 1 2 3 4)

- Scheme Procedure:
**vector-unfold***f length initial-seed …* The fundamental vector constructor. Create a vector whose length is

`length`and iterates across each index k from 0 up to`length`- 1, applying`f`at each iteration to the current index and current seeds, in that order, to receive n + 1 values: 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.(vector-unfold (lambda (i x) (values x (- x 1))) 10 0) ⇒ #(0 -1 -2 -3 -4 -5 -6 -7 -8 -9) (vector-unfold values 10) ⇒ #(0 1 2 3 4 5 6 7 8 9)

- Scheme Procedure:
**vector-unfold-right***f length initial-seed …* Like

`vector-unfold`

, but it uses`f`to generate elements from right-to-left, rather than left-to-right.(vector-unfold-right (lambda (i x) (values x (+ x 1))) 10 0) ⇒ #(9 8 7 6 5 4 3 2 1 0)

- Scheme Procedure:
**vector-copy***vec [start [end [fill]]]* Allocate a new vector whose length is

`end`-`start`and fills it with elements from`vec`, taking elements from`vec`starting at index`start`and stopping at index`end`.`start`defaults to 0 and`end`defaults to the value of`(vector-length vec)`

. If`end`extends beyond the length of`vec`, the slots in the new vector that obviously cannot be filled by elements from`vec`are filled with`fill`, whose default value is unspecified.(vector-copy '#(a b c d e f g h i)) ⇒ #(a b c d e f g h i) (vector-copy '#(a b c d e f g h i) 6) ⇒ #(g h i) (vector-copy '#(a b c d e f g h i) 3 6) ⇒ #(d e f) (vector-copy '#(a b c d e f g h i) 6 12 'x) ⇒ #(g h i x x x)

- Scheme Procedure:
**vector-reverse-copy***vec [start [end]]* Like

`vector-copy`

, but it copies the elements in the reverse order from`vec`.(vector-reverse-copy '#(5 4 3 2 1 0) 1 5) ⇒ #(1 2 3 4)

- Scheme Procedure:
**vector-append***vec …* Return a newly allocated vector that contains all elements in order from the subsequent locations in

`vec`....(vector-append '#(a) '#(b c d)) ⇒ #(a b c d)

- Scheme Procedure:
**vector-concatenate***list-of-vectors* Append each vector in

`list-of-vectors`. Equivalent to`(apply vector-append list-of-vectors)`

.(vector-concatenate '(#(a b) #(c d))) ⇒ #(a b c d)
