MATLAB Function Reference

transpose (timeseries) - Transpose timeseries object

Syntax

ts1 = transpose(ts)

Description

ts1 = transpose(ts) returns a new timeseries object ts1 with IsTimeFirst value set to the opposite of what it is for ts. For example, if ts has the first data dimension aligned with the time vector, ts1 has the last data dimension aligned with the time vector.

Remarks

The transpose function that is overloaded for the timeseries objects does not transpose the data. Instead, this function changes whether the first or the last dimension of the data is aligned with the time vector.

Note   To transpose the data, you must transpose the Data property of the time series. For example, you can use the syntax transpose(ts.Data) or (ts.Data).'. Data must be a 2-D array.

Consider a time series with 10 samples with the property IsTimeFirst = True. When you transpose this time series, the data size is changed from 10-by-1 to 1-by-1-by-10. Note that the first dimension of the Data property is shown explicitly.

The following table summarizes how the size for time-series data (up to three dimensions) display before and after transposing.

Data Size Before and After Transposing

Examples

Suppose that a timeseries object ts has ts.Data size 10-by-3-by-2 and its time vector has a length of 10. The IsTimeFirst property of ts is set to true, which means that the first dimension of the data is aligned with the time vector. transpose(ts) modifies the timeseries object such that the last dimension of the data is now aligned with the time vector. This permutes the data such that the size of ts.Data becomes 3-by-2-by-10.
