Summary: Today we consider vectors, which serve as alternates to lists. Vectors differ from lists in three primary ways: vectors have fixed size, vectors are indexed, and vectors are mutable.
(vector val1 ... valn): Create a vector
(make-vector length val): Make a vector of specified length, with duplicates of val as the contents.
(vector-ref vector position): Extract a value from a vector.
(vector-set! vector position newvalue): Change an element of a vector.
I usually create these pages
on the fly, which means that I rarely
proofread them and they may contain bad grammar and incorrect details.
It also means that I tend to update them regularly (see the history for
more details). Feel free to contact me with any suggestions for changes.
