Create an insCF filter object. Get the default orientation value by using the stateparts object function.

filter = insCF;
stateparts(filter,"Orientation")

ans = 1×4

     1     0     0     0

Specify a new orientation value. Verify the updated value of the orientation part of the filter's state.

stateparts(filter,"Orientation",[0.005782462930365 -0.135766868853727 -0.057153855377551 -0.989073989780136]);
stateparts(filter,"Orientation")

ans = 1×4

    0.0058   -0.1358   -0.0572   -0.9891

Reset the filter, and check that the orientation part of the filter's state has returned to its default value.

reset(filter)
stateparts(filter,"Orientation")
