removeParameter
Remove parameter from sdo.ParameterSpace or
sdo.GriddedSpace object
Description
Examples
Create an sdo.ParameterSpace object, ps, for the Ac and K parameters of the sdoHydraulicCylinder model.
load_system('sdoHydraulicCylinder'); p = sdo.getParameterFromModel('sdoHydraulicCylinder',{'Ac','K'}); ps = sdo.ParameterSpace(p)
ps =
ParameterSpace with properties:
ParameterDistributions: [1×2 prob.UniformDistribution]
RankCorrelation: []
Notes: []
ParameterNames: {'Ac' 'K'}
Options: [1×1 sdo.SampleOptions]
Remove K from ps.
ps = removeParameter(ps,p(2))
ps =
ParameterSpace with properties:
ParameterDistributions: [1×1 prob.UniformDistribution]
RankCorrelation: []
Notes: []
ParameterNames: {'Ac'}
Options: [1×1 sdo.SampleOptions]
Remove Ac from ps using the parameter name.
ps = removeParameter(ps,'Ac');Open the sdoCSTR model and extract continuous parameters A, h, FeedCon0, and FeedTemp0. Assign values to these parameters for gridded sampling and define the parameter space.
mdl = "sdoCSTR"; open_system(mdl); p = sdo.getParameterFromModel(mdl,{'A','h','FeedCon0','FeedTemp0'}); Avals = {0.2 0.6 1.0 1.4 1.8 2.2}; hvals = {0.5 1.5 2.5 3.5}; Convals = {9.5 10.0 10.5}; Tempvals = {250,275,300}; ps0 = sdo.GriddedSpace(p,{Avals,hvals,Convals,Tempvals});
Suppose that you decide not to sample A and h as part of this parameter space. Remove these parameters by providing their names to removeParameters.
ps = removeParameter(ps0,{'A','h'})ps =
GriddedSpace with properties:
ParameterValues: {{1×3 cell} {1×3 cell}}
Notes: []
Spaces: {1×0 cell}
ParameterNames: {'FeedCon0' 'FeedTemp0'}
Options: [1×1 sdo.GriddingOptions]
removeParameter updates ParameterValues and ParameterNames to reflect the reduced set of parameters in the space.
Input Arguments
Parameter space to remove parameters from, specified as an
sdo.ParameterSpace or sdo.GriddedSpace
object.
Parameters to remove from ps0, specified as one of the
following:
Character vector, cell array of character vectors, or string containing the names of the parameters to remove from
ps0. For example,'A1',{'A1','A2'}, or"A1".param.Continuousobject,param.Discreteobject, or vector of parameter objects. Usually, you obtain these objects usingsdo.getParameterFromModelorsdo.getStateFromModel.
Output Arguments
Updated parameter space, returned as an sdo.ParameterSpace or
sdo.GriddedSpace object. removeParameter removes
the parameter or parameters specified in p, setting
ps.ParameterNames to reflect the removal. The function also sets
ps.ParameterDistributions (for randomly sampled parameter spaces)
or ps.ParameterValues (for gridded parameter spaces) to reflect the
removed parameters.
