Returns a sequence equivalent to @scheme[vec].
@defproc[(in-vector [vec vector?] [start number?] [stop number?] [step number?]) sequence?]{
Returns a sequence equivalent to @scheme[vec]. The optional
arguments @scheme[start], @scheme[stop], and @scheme[step]
are as for @scheme[in-range]. The single-argument case
@scheme[(in-vector vec)] is equivalent to @scheme[(in-vector 0
(vector-length vec) 1)]. The first number in the sequence is
@scheme[start], and each successive element is generated by
adding @scheme[step] to the previous element. The sequence
stops before an element that would be greater or equal to
@scheme[end] if @scheme[step] is non-negative, or less or
equal to @scheme[end] if @scheme[step] is negative.
