Since R2022a

collapse all in page

Syntax

data = readall(tdmsds)

Description

data = readall(tdmsds) reads all the data in the datastore specified by tdmsds, and returns a cell array of tables or timetables. Each element of the cell array corresponds to a channel group in the datastore file data.

The function returns a cell array of tables or a cell array of timetables, depending on the value of the tdmds.RowTimes property. See tdmsDatastore.

After the readall function returns all the data, it resets tdmsds to point to the beginning of the datastore.
