Parameter Tuning via MATLAB Commands

The Model Parameter Configuration dialog is the recommended way to see or set the attributes of tunable parameters. However, you can also use MATLAB get_param and set_param commands.

The following commands return the tunable parameters and/or their attributes:

• get_param(gcs, 'TunableVars')
• get_param(gcs, 'TunableVarsStorageClass')
• get_param(gcs, 'TunableVarsTypeQualifier')

The following commands declare tunable parameters or set their attributes:

• set_param(gcs, 'TunableVars', str)

• The argument str (string) is a comma-separated list of variable names.

• set_param(gcs, 'TunableVarsStorageClass', str)

• The argument str (string) is a comma-separated list of storage class settings.

  The valid storage class settings are:

  • Auto
  • ExportedGlobal
  • ImportedExtern
  • ImportedExternPointer

• set_param(gcs, 'TunableVarsTypeQualifier', str)

• The argument str (string) is a comma-separated list of storage type qualifiers.

The following example declares the variable k1 to be tunable, with storage class ExportedGlobal and type qualifier const.

• set_param(gcs, 'TunableVars', 'k1')
  set_param(gcs, 'ExportedGlobal')
  set_param(gcs, 'TunableVarsTypeQualifier','const')
