Types ¶
type Matrix ¶
type Matrix struct {
// contains filtered or unexported fields
}
Matrix represents matrix object
func New ¶
New returns a new matrix provided given the order . Ie rows and cols. Values are the values of a martix as cols, If less values are provided than the order zeros are used to fill the matrix .
Example ¶
package main
import (
"fmt"
"github.com/Duncodes/mathlib/matrix"
)
func main() {
m := matrix.New(1, 2, 4, 3)
fmt.Println(m)
}
Output: 4 3
func NewFromArray ¶
NewFromArray creates new Matrix given a 2d sclice
Example ¶
This creates a new Matrix from [][]float64
package main
import (
"fmt"
"github.com/Duncodes/mathlib/matrix"
)
func main() {
m := matrix.NewFromArray([][]float64{{1, 2}, {1, 2}})
fmt.Println(m)
}
Output:
func Zero ¶
Zero creates a zero matrix
Example ¶
package main
import (
"fmt"
"github.com/Duncodes/mathlib/matrix"
)
func main() {
m := matrix.Zero(1, 3)
fmt.Println(m)
}
Output: 0 0 0
func (*Matrix) Get ¶
Get gets the data item in the row and col provided, Note this is zero besed indexed.Hence the first element of the matrix is accessed using Get(0,0)
func (*Matrix) Set ¶
Set changes the data value at row , col provided. Note set has a zero base index ie the first element of the first col is accessed via Set(0,0) not Set(1,1)
