Usage
Requiring the Module
const matrixTransformers = require('@pelevesque/matrix-transformers')Requiring a Particular Transformation
const rotateMatrixClockwise = require('@pelevesque/matrix-transformers').rotate90Available Transformations
- rotate90
- rotate180
- rotate270
- reflectHorizontally
- reflectVertically
Examples
const matrix = [
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]
]
const transformed = matrixTransformers.reflectHorizontally(matrix)
// result
transformed = [
[3, 2, 1],
[6, 5, 4],
[9, 8, 7]
]const matrix = [
[1, 2],
[3, 4],
[5, 6]
]
const transformed = matrixTransformers.rotate270(matrix)
// result
transformed = [
[2, 4, 6],
[1, 3, 5]
