Option set for
opt = iv4Options
opt = iv4Options(Name,Value)
comma-separated pairs of
the argument name and
Value is the corresponding value.
Name must appear inside quotes. You can specify several name and value
pair arguments in any order as
'InitialCondition'— Handling of initial conditions
Handling of initial conditions during estimation, specified as one of the following values:
'zero' — The initial condition
is set to zero.
'estimate' — The initial
condition is treated as an independent estimation parameter.
'auto' — The software chooses
the initial condition handling method based on the estimation data.
'Advanced'— Additional advanced options
Additional advanced options, specified as a structure with the following fields:
MaxSize — Specifies the
maximum number of elements in a segment when input-output data is
split into segments.
MaxSize must be a positive integer.
StabilityThreshold — Specifies
thresholds for stability tests.
StabilityThreshold is a structure with the
s — Specifies the location
of the right-most pole to test the stability of continuous-time models.
A model is considered stable when its right-most pole is to the left
z — Specifies the maximum
distance of all poles from the origin to test stability of discrete-time
models. A model is considered stable if all poles are within the distance
opt = iv4Options;
Create an options set for
iv4 using the
'backcast' algorithm to initialize the state. Set
opt = iv4Options('InitialCondition','backcast','Display','on');
Alternatively, use dot notation to set the values of
opt = iv4Options; opt.InitialCondition = 'backcast'; opt.Display = 'on';
