make-typed-aref-vector

Makes a vector that can be accessed efficiently.

system

make-typed-aref-vector byte-length => vector

byte-length

A non-negative fixnum.

vector

A vector.

The function make-typed-aref-vector returns a vector which is suitable for efficient access at compiler optimization level safety = 0.

byte-length is measured in 8-bit bytes.

Use typed-aref to access vector efficiently.

To make a typed vector of the type (unsigned-byte 32) or single-float with length 10:


(make-typed-aref-vector (* 10 4))

To make a typed vector of the type double-float with length 10:


(make-typed-aref-vector (* 10 8))
