Functions ¶
Types ¶
type Matrix ¶
type Matrix[T comparable] struct { Data []T Size Vec }
func NewFromReader ¶
NewFromReader reads lines from the Reader and builds a new Matrix[byte] where each line is a row of the matrix, starting from the top. Each line must be of the same length, else an error will be returned.
func (*Matrix[T]) At ¶
At returns the value present at a coordinate. It's the responsibility of the user to check that the coordinate exists within the Matrix with In.
func (*Matrix[T]) AtCoord ¶
AtCoord returns the value present at a coordinate. It's the responsibility of the user to check that the coordinate exists within the Matrix with InCoord.
func (*Matrix[T]) Coords ¶
Coords will return an iterator over all the coordinates that exist in the matrix.
func (*Matrix[T]) Copy ¶
Copy copies data from a matrix into the current matrix. If geometries are different, an error will be returned.
func (*Matrix[T]) Fill ¶
func (m *Matrix[T]) Fill(value T)
Fill will fill the matrix with a given value.
func (*Matrix[T]) Find ¶
Find searches for a value in the Matrix and returns a coordinate of the first match and a boolean indicating if the value was found.
func (*Matrix[T]) SetAt ¶
SetAt sets the value present at a coordinate. It's the responsibility of the user to check that the coordinate exists within the Matrix with In.
func (*Matrix[T]) SetAtCoord ¶
SetAtCoord sets the value present at a coordinate. It's the responsibility of the user to check that the coordinate exists within the Matrix with InCoord.
