getSensitivity


Sensitivity function at specified point using slLinearizer or slTuner interface


Syntax


linsys = getSensitivity(s,pt)
linsys = getSensitivity(s,pt,temp_opening)
linsys = getSensitivity( ___ ,mdl_index)


[linsys,info] = getSensitivity( ___ )


Description


linsys = getSensitivity(s,pt) returns the sensitivity function on page 15-363 at
the specified analysis point for the model associated with the slLinearizer or slTuner
interface, s.


The software enforces all the permanent openings on page 15-365 specified for s when it
calculates linsys. If you configured either s.Parameters, or s.OperatingPoints, or
both, getSensitivity performs multiple linearizations and returns an array of
sensitivity functions.


linsys = getSensitivity(s,pt,temp_opening) considers additional, temporary,
openings at the point specified by temp_opening. Use an opening, for example, to
calculate the sensitivity function of an inner loop, with the outer loop open.


linsys = getSensitivity( ___ ,mdl_index) returns a subset of the batch
linearization results. mdl_index specifies the index of the linearizations of interest, in
addition to any of the input arguments in previous syntaxes.


Use this syntax for efficient linearization, when you want to obtain the sensitivity function
for only a subset of the batch linearization results.


[linsys,info] = getSensitivity( ___ ) returns additional linearization
information.
