1 Vectors

(require (planet wmfarr/plt-linalg:1:9/vector))

The "plt-linalg.plt" package represents vectors as f64vectors.

1.1 Contracts for Vectors

(f64vector-same-length/c v) → flat-contract?

v : f64vector?

Produces a contract which matches f64vectors of the same length as v.

1.2 Procedures for Vectors

(f64vector-norm v) → (>=/c 0)

v : f64vector?

Computes the two-norm of v.

(f64vector-copy v) → f64vector?

v : f64vector?

Produces a copy of v.

(f64vector-scale v x) → f64vector?

v : f64vector?

x : real?

Produces a new f64vector whose elements are those of v scaled (multiplied) by x.

(f64vector-add v1 v2) → f64vector?

v1 : f64vector?

v2 : (f64vector-same-length/c v1)

Produces a new f64vector whose elements are the sum of corresponding elements of v1 and v2.

(f64vector-sub v1 v2) → f64vector?

v1 : f64vector?

v2 : (f64vector-same-length/c v1)

Produces a new f64vector whose elements are the difference of corresponding elements of v1 and v2.

(f64vector-dot v1 v2) → real?

v1 : f64vector?

v2 : (f64vector-same-length/c v1)

Computes the dot product of v1 and v2.
