ndarray-scratch

ndarray-scratch

A simple wrapper for typedarray-pool. I got tired of manually constructing ndarrays from typedarrays, and so this module saves some keystrokes/sanity.

Example

var pool = require("ndarray-scratch")
 
//Create a temporary typed array 
var x = pool.malloc([100,100])
 
//Do stuff with x 
 
//Release x 
pool.free(x)

Install

npm install ndarray-scratch

API

var pool = require("ndarray-pool")

pool.malloc(shape[, dtype])

Allocates a temporary ndarray

  • shape is the shape of the array to allocate
  • dtype is the dtype of the array to allocate (default "double")

Returns a temporary ndarray

pool.zeros(shape[,dtype])

Creates a scratch ndarray initialized to 0

  • shape is the shape of the resulting array
  • dtype is the datatype of the array (default "double")

Returns A temporary ndarray initialized to 0

pool.ones(shape[,dtype])

Creates a scratch ndarray initialized to 1

  • shape is the shape of the resulting array
  • dtype is the datatype of the array (default "double")

Returns A temporary ndarray initialized to 1

pool.eye(shape[,dtype])

Creates a scratch ndarray initialized to 1 if all indices equal, 0 otherwise.

  • shape is the shape of the resulting array
  • dtype is the datatype of the array (default "double")

Returns A temporary ndarray initialized to the identity matrix

pool.free(array)

Releases a temporary ndarray

  • array is the ndarray to release.

pool.clone(array)

Creates a copy of an ndarray with row-major order.

  • array is an ndarray

Returns A temporary copy of array
