Syntax

removeData(lanedata,Timestamp=timestamps)
removeData(lanedata,RowIndices=rowIndices)

Description

removeData(lanedata,Timestamp=timestamps) removes lane information for the specified timestamps timestammps from the laneData object lanedata.

example

removeData(lanedata,RowIndices=rowIndices) removes lane information for the specified row indices rowIndices from the laneData object lanedata.

Note

This function requires the Scenario Builder for Automated Driving Toolbox™ support package. You can install Scenario Builder for Automated Driving Toolbox from the Add-On Explorer. For more information about installing add-ons, see Get and Manage Add-Ons.

This example uses:

Open Live Script

Load an initialized LaneData object into the workspace.

data = load("laneDataObject.mat");
ld = data.ld;

Display the details of the laneData object.

disp(ld)
  laneData with properties:

           TimeStamp: [1158×1 double]

           StartTime: 0
             EndTime: 57.8515
          NumSamples: 1158

Specify the row indices for which to remove data from the laneData object.

idxs = 1:5;

Remove the first five rows of data from the laneData object.

removeData(ld,RowIndices=idxs)

Display the details of thes laneData object after data removal.

Input Arguments

collapse all

Recorded lane data, specified as a laneData object.

Timestamps for which to remove lane information, specified as a nonnegative scalar or an N-element vector. N is the number of timestamps. Units are in seconds.

After timestamp removal, the lanedata object automatically arranges the remaining timestamps in increasing order.

Data Types: double

Row indices of lane data to remove, specified as a positive integer or an N-element vector of positive integers. N is the number of rows of the lanedata input from which to remove data. Values must be in the range [1, NumSamples], where NumSamples is the value of the NumSamples property of the input laneData object lanedata.

Data Types: single | double | uint8 | uint16 | uint32 | uint64
