Part of a timeseries strictly before an event.

Category: Language Fundamentals > Data Types

Syntax

tsout = gettsbeforeevent(ts, event)

Returns the samples with time earlier than the event.

Description

Events are added with addevent. The result is a new timeseries; its Time and Data hold the selected samples. A sample exactly at the event time is excluded; use gettsbeforeatevent to keep it.

Input arguments

ts: timeseries with at least one event.
event: Event name as text, or the event index.

Output arguments

tsout: timeseries with the selected samples.

Example

Samples before an event

ts = timeseries((10:10:50)', (0:4)');
ts = addevent(ts, 'start', 1.5);
ts = addevent(ts, 'stop', 3.5);
r = gettsbeforeevent(ts, 'stop');
disp(r.Time')
disp(r.Data')

Output

     0     1     2     3
    10    20    30    40
