setValues
Description
Examples
Change Grid Values in Gridded Parameter Space
Open the sdoCSTR
model and create a gridded parameter space for model parameters A
and h
.
mdl = "sdoCSTR"; open_system(mdl); p = sdo.getParameterFromModel(mdl,{'A','h'}); gs0 = sdo.GriddedSpace(p)
gs0 = GriddedSpace with properties: ParameterValues: {{1x2 cell} {1x2 cell}} Notes: [] Spaces: {1x0 cell} ParameterNames: {'A' 'h'} Options: [1x1 sdo.GriddingOptions]
Because you do not specify allowed grid values for the two parameters, sdo.GriddedSpace
assigns the default values: 10% less than the parameter nominal value, the nominal value, and 10% more than the nominal value. Change the allowed values for both parameters to a specified set.
Avals1 = {0.2 0.6 1.0 1.4 1.8 2.2}; hvals1 = {0.5 1.5 2.5 3.5}; gs1 = setValues(gs0,p,{Avals1,hvals1})
gs1 = GriddedSpace with properties: ParameterValues: {{1x2 cell} {1x2 cell}} Notes: [] Spaces: {1x0 cell} ParameterNames: {'A' 'h'} Options: [1x1 sdo.GriddingOptions]
setValues
replaces the allowed values for both parameters with the new sets of values.
Now, set new values for the parameter h
only. This time, specify the parameter by its name instead of by a parameter object.
hvals2 = {0.2 0.5 1.0 1.2 1.8};
gs2 = setValues(gs0,'h',{hvals2})
gs2 = GriddedSpace with properties: ParameterValues: {{1x2 cell} {1x2 cell}} Notes: [] Spaces: {1x0 cell} ParameterNames: {'A' 'h'} Options: [1x1 sdo.GriddingOptions]
Here, setValues
replaces the allowed values for h
with the new set of values.
Input Arguments
gs0
— Gridded parameter space
sdo.GriddedSpace
object
Gridded parameter space in which to set parameter values, specified as an
sdo.GriddedSpace
object.
p
— Parameters to update
character vector | cell array of character vectors | string | parameter object | vector of parameter objects
Parameters to update in gs0
, specified as one of the
following:
Character vector, cell array of character vectors, or string containing the names of the parameters to update in
gs0
. For example,'A1'
,{'A1','A2'}
, or"A1"
.param.Continuous
object,param.Discrete
object, or vector of parameter objects. Usually, you obtain these objects usingsdo.getParameterFromModel
orsdo.getStateFromModel
.
values
— Parameter values for gridded sampling
cell array of cell arrays
Parameter values for gridded sampling, specified as a cell array of cell arrays
providing the allowed values for each parameter in p
. For instance,
if p
contains two parameters, one that can take values (1, 2, 3)
and another that can take values (10, 20, 30), then use values =
{{1,2,3},{10,20,30}}
. Use this argument when adding parameters for gridded
sampling to an sdo.GriddedSpace
object.
