read
Class: matlab.io.datastore.sdidatastore
Package: matlab.io.datastore
Read a chunk of data from an sdidatastore
Syntax
data = sdi_ds.read
Description
reads a chunk of samples
from the data
= sdi_ds.readmatlab.io.datastore.sdidatastore
, sdi_ds
,
and updates the read position for sdi_ds
to the point following the
endpoint of the returned data. The samples are returned in the timetable
, data
. The number of samples read by the
read
method vary, and the returned timetable
always fits into memory. Use the read
method to incrementally process
signals that are too large to fit into memory.
Output Arguments
Examples
Alternatives
You can use your matlab.io.datastore.sdidatastore
to create a tall
timetable to process signals too large to fit into memory. The tall timetable handles
loading and processing the chunks of signal data for you. The
matlab.io.datastore.sdidatastore
reference page includes an
example that shows how to process your data using a tall timetable. For more information
about working with tall timetables, see Tall Arrays.
