Table A-17: Model.rtw Model Parameters Record
Variable/Record Name

Description
|
ModelParameters {
|
|
NumParameters
|
Total number of unique parameter values (sum of next 5 fields).
|
NumInrtP
|
Number of parameter values in "rtP" parameter vector (realized as a struct). These are visible to external mode and possibly shared by multiple blocks.
|
NumInlinedUnlessRolled
|
Number of inlined parameter values. These are inlined, unless the roll threshold causes them to be placed in global memory. These parameters are not shared by multiple blocks.
|
NumExportedGlobal
|
Number of exported global parameters values. May be shared by multiple blocks.
|
NumImportedExtern
|
Number of imported parameter values. May be shared by multiple blocks.
|
NumImportedExternPointer
|
Number of parameter values that are accessed via imported extern pointers. May be shared by multiple blocks.
|
ParameterDefaults {
|
Default values for the following Parameter records.
|
DataTypeIdx
|
0: Default is real_T data type.
|
ComplexSignal
|
no: Default is non-complex
|
Tunable
|
no: Default value is not tunable.
|
StorageClass
|
Auto: Default value is Auto (Real-Time Workshop declares the memory).
|
TypeQualifier
|
"": Default is no type qualifier.
|
IsSfcnSizePrm
|
0: Default is not an S-function sizes parameter (only used by non-inlined S-functions)
|
}
|
|
Parameter {
|
|
Identifier
|
Identifier used in the generated code.
|
Tunable
|
If inlined parameters check box is off, then all parameter values are tunable (they will reside in the rtP vector). If inlined is on, then tunable means that this parameter has been selectively non- inlined. It will be placed in memory according to the Storage class. Note that the default value is 'no' (in which case this field is not written).
|
RequiredInP
|
Parameter required in rtP vector, 1 for the Accelerator, Rapid Simulation Target, External Mode; 0 otherwise.
|
StorageClass
|
Specifies where to declare/place this parameter value in memory
(Auto, ExportedGlobal, ImportedExtern, ImportedExternPointer). Default value is Auto in which case this field is not written to the model.rtw file.
|
TypeQualifier
|
String used as a type qualifier for the declaration of the parameter (e.g., "static").
|
Value
|
Evaluated value of this parameter.
|
Dimensions
|
Actual dimensions of this parameter value. Note, it is possible for blocks to have matrix values written as a column-major vector. This field contains the dimensions of the data prior to the flattening of the vector to column-major.
|
DatatTypeIdx
|
Data type index into the data type table (CompiledModel.DataTypes.DataType).
|
ComplexSignal
|
yes or no, is this a complex signal?
|
IsSfcnSizePrm
|
1 if this is an S-function sizes parameter, 0 otherwise.
|
ReferencedBy
|
An N-by-3 matrix. Each row specifies a system, block, parameter index triplet that identifies a usage of this parameter value. If N>1, then this parameter value is shared by multiple blocks.
