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
