Types

type Vektor

type Vektor struct {
	// contains filtered or unexported fields
}

Vektor implements the Gridder interface in the c stlyle as seen in stam https://www.josstam.com/_files/ugd/cf1fd6_9989229efbd34a26ba5ccd913721a2ac.pdf

Basically a 1D vector stores the 2D values and two grid coordinates are translated to a single index

Perhaps the golang offers more performant or idomatic approaches - multi dimension slice, prolly better? - array (sans slice), doubtful? In the meantime, we have some isolation via the interface

func New

func New(dim int) *Vektor

New creates a vektor, given:

dim: width and height of grid

func (*Vektor) Get

func (vk *Vektor) Get(i, j int) float64

Get gets the value for a given cell

func (*Vektor) Set

func (vk *Vektor) Set(i, j int, val float64)

Set sets a value for the given cell

func (*Vektor) Swap

func (vk *Vektor) Swap(other ifc.Gridder)

Swap swaps the value slices of two vektors for this to work: - pass in pointers to the vektors (of course) - respective vektors hold pointers to value slices "type vektorAlt []float64" with swapping in layer could be cleaner? Todo: yes!
