Syntax

[res,resCov] = residualgyro(FUSE,gyroReadings,gyroCovariance)

Description

[res,resCov] = residualgyro(FUSE,gyroReadings,gyroCovariance) computes the residual, res, and the innovation covariance, resCov, based on the gyroscope readings and the corresponding covariance.

Create an insfilterAsync object and display its state.

filter = insfilterAsync;
disp(filter.State')
    1.0000         0         0         0         0         0         0         0         0         0         0         0         0         0         0         0         0         0         0         0         0         0   27.5550   -2.4169  -16.0849         0         0         0

Define an gyroscope measurement with its covariance. 

angularVel = [1 1 1] 
angularVel = 1×3

     1     1     1


angularVelCovariance = 0.01*diag([1 1 1]);

Obtain the residual of the data.

[res,resCovariance] = residualgyro(filter,angularVel,angularVelCovariance)
res = 1×3

     1     1     1


resCovariance = 3×3

    0.0120         0         0
         0    0.0120         0
         0         0    0.0120
