Motor Control Blockset examples: Using variant source block

1 view (last 30 days)
a Variant source block is used in 'mcb_pmsm_operating_mode_f28379d.slx' model example to switch betwen SIMulation mode and CODE-generation mode. Inside Varian source block, there are two variables: mcb_isCodeGenVar() and mcb_isSimVar().
Could you please tell me where and how are those variables set? When the model decides what mode is to be chosen? Do I have to play with a Variant manager?

Those are functions, not variables. They are p-coded M-Files that are shipped with the example. Type the following to see where the files exist:
who mcb_isCodeGenVar

Perfect. Thanks.
So, mcb_isCodeGenVar() function (and associated p-file) is a specific item of MotorControl Toolbox. Please, confirm.
Is there any document with the list and of those 'integrated' functions for the MC toolbox (including a function description and applicability)?

Yes, those two functions are part of the Motor Control Toolbox. Neither of these two functions are currently documented in MATLAB Help. I'll add a change request to have them added to the help documentation.
