perturb
Syntax
Description
applies the perturbations defined on the object, offsets
= perturb(obj
)obj
and returns the
offset values. You can define perturbations on the object by using the perturbations
function.
Examples
Create an insSensor
object.
sensor = insSensor
sensor = insSensor with properties: MountingLocation: [0 0 0] m RollAccuracy: 0.2 deg PitchAccuracy: 0.2 deg YawAccuracy: 1 deg PositionAccuracy: [1 1 1] m VelocityAccuracy: 0.05 m/s AccelerationAccuracy: 0 m/s² AngularVelocityAccuracy: 0 deg/s TimeInput: 0 RandomStream: 'Global stream'
Define the perturbation on the RollAccuracy
property as three values with an equal possibility each.
values = {0.1 0.2 0.3}
values=1×3 cell array
{[0.1000]} {[0.2000]} {[0.3000]}
probabilities = [1/3 1/3 1/3]
probabilities = 1×3
0.3333 0.3333 0.3333
perturbations(sensor,'RollAccuracy','Selection',values,probabilities)
ans=7×3 table
Property Type Value
_________________________ ___________ ______________________________________
"RollAccuracy" "Selection" {1×3 cell} {[0.3333 0.3333 0.3333]}
"PitchAccuracy" "None" {[ NaN]} {[ NaN]}
"YawAccuracy" "None" {[ NaN]} {[ NaN]}
"PositionAccuracy" "None" {[ NaN]} {[ NaN]}
"VelocityAccuracy" "None" {[ NaN]} {[ NaN]}
"AccelerationAccuracy" "None" {[ NaN]} {[ NaN]}
"AngularVelocityAccuracy" "None" {[ NaN]} {[ NaN]}
Perturb the sensor
object using the perturb function.
rng(2020) perturb(sensor); sensor
sensor = insSensor with properties: MountingLocation: [0 0 0] m RollAccuracy: 0.5 deg PitchAccuracy: 0.2 deg YawAccuracy: 1 deg PositionAccuracy: [1 1 1] m VelocityAccuracy: 0.05 m/s AccelerationAccuracy: 0 m/s² AngularVelocityAccuracy: 0 deg/s TimeInput: 0 RandomStream: 'Global stream'
The RollAccuracy
is perturbed to 0.5
deg.
Input Arguments
Object for perturbation, specified as an object. The objects that you can perturb include:
Output Arguments
Property offsets, returned as an array of structures. Each structure contains these fields:
Field Name | Description |
---|---|
Property | Name of perturbed property |
Offset | Offset values applied in the perturbation |
PerturbedValue | Property values after the perturbation |
Version History
Introduced in R2024a
