partition

(Not recommended) Partition bigimageDatastore

Since R2019b

The partition function of the bigimageDatastore object is not recommended. Use the partition function associated with the blockedImageDatastore object instead. For more information, see Compatibility Considerations.

Syntax

outds = partition(bigds,n,index)

Description

outds = partition(bigds,n,index) partitions big image datastore bigds into the number of parts specified by n and returns the partition corresponding to the index index.

Input Arguments

bigds — Big image datastore

bigimageDatastore object

Big image datastore, specified as a bigimageDatastore object.

n — Number of partitions

positive integer

Number of partitions, specified as a positive integer.

Example: 3

Data Types: double

index — Index

positive integer

Index, specified as a positive integer.

Example: 1

Data Types: double

Output Arguments

outds — Output datastore

bigimageDatastore object

Output datastore, returned as a bigimageDatastore object.

Version History

Introduced in R2019b

R2021a: partition function is not recommended

Starting in R2021a, the bigimageDatastore object and its object functions, which operate on data from bigimage objects, are no longer recommended. Instead, use the blockedImageDatastore object and its object functions, which operate on data from blockedImage objects. The blockedImage object offers several advantages including extension to N-D processing, a simpler interface, and custom support for reading and writing nonstandard image formats.

Although there are no plans to remove the bigimageDatastore object and its partition function at this time, switch to the blockedImageDatastore object and its partition function to take advantage of the additional capabilities and flexibility.
