Timetables

Time-stamped data in tabular form

timetable is a type of table that associates a time with each row. Like table, the timetable data type can store column-oriented data variables that have different data types and sizes, as long as they have the same number of rows. In addition, timetables provide time-specific functions to align, combine, and perform calculations with one or more timetables. For more information, see Create Timetables or watch Managing Time-Stamped Tabular Data with Timetables.

Topics

Create Timetables

Create timetables to associate times with rows of data. Adjust data in a timetable to a different set of times, and synchronize data in multiple timetables.

Clean Timetable with Missing, Duplicate, or Nonuniform Times

Clean timetables that have missing, duplicate, or irregular times, and produce regular timetables.

Resample and Aggregate Data in Timetable

Resample or aggregate data in a timetable to a new vector of row times.

Access Data in a Table

Indexing into tables with parentheses, curly braces, and dot notation has different results. You can use indexing to create a table that is a subset of a larger table or to create an array from data in a table.
