Repeat an ndarray

Introduction

This module takes an input ndarray and repeats it some number of times in each dimension.

Examples

tile = require('ndarray-tile')
ndarray = require('ndarray')

epeat a vector:
(ndarray(new Float64Array([1, 2, 3])), [2])
> 1 2 3 1 2 3


epeat a vector in a second dimension:
(ndarray(new Float64Array([1, 2, 3])), [1, 2])
> 1 1
  2 2
  3 3


ile a matrix in two dimensions:
(ndarray(new Float64Array([1, 2, 3, 4]), 2, 2]), [2, 2])
> 1 2 1 2
  3 4 3 4
  1 2 1 2
  3 4 3 4

Installation

m install ndarray-tile

API

require('ndarray-tile')([output,] input, reps)

Tile ndarray input a number of times according to reps in each dimension.

Arguments:

• output (optional): Optional output array. If not provided, storage is allocated using ndarray-scratch.
• input: The input ndarray to be tiled
• reps: An Array containing The number of repetitions in each dimension. Each entry must be an integer greater than zero.
• If the length of reps is less than the dimemsionality of input, the ommitted dimensions are implicitly assumed to be one.
• If the length of reps is greater than the dimensionality of input, then input is tiled in the new dimensions as specified.

Returns: a reference to the tiled output
