Parameter Record Defaults

The ParameterDefaults record contains default entries for parameters. These records are used throughout the model when no field is explicitly provided for a model parameter. For example, the default DataTypeIdx is 0, which corresponds to real_T. The default entry for ComplexSignals is no. Other entries such as the Tunable field is controlled by the Inline parameters check box. If for a given block instance, a Parameter record does not contain a specific entry for these fields, then the value from the ParameterDefaults is applied.

Description

ParameterDefaults {

Record for default values of block variables that aren't explicitly written in the block parameter records. The block parameter records only contain nondefault values for the following variables.

  MemoryMapIdx

[-1,-1,-1]: used to populate global data map record (GlobalMemoryMap) during code generation. Refer to
matlabroot/rtw/c/tlc/mw/globalmaplib.tlc for usage information on the MemoryMapIdx field.
