Usage

Requiring the Module

const matrixTransformers = require('@pelevesque/matrix-transformers')

Requiring a Particular Transformation

const rotateMatrixClockwise = require('@pelevesque/matrix-transformers').rotate90

Available 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]
]
