about setting setBlockParameter (blkParam, paramVal)

8 views (last 30 days)
I have a qusestion about setting setBlockParameter.
In example,
blkParam is 'Gain' and 'Position'.
Question for here.
  1. Are these 'Gain' and 'Position' is designated text arrays in Metlab?
  2. Can't I set it to my own text I want?
In example.
paramVal is '40'
Question for here.
3. I want to change value '40' to 1x4 maxtrix [1 0 0 0], how can i change the value?

A1. Gain and Position are block parameters. Position is a paramter that is common to all blocks. More info here Common Block Properties Gain is a block parameter unique to the Gain block. More info here Block-Specific Parameters.
A2. No, you can't change the names of those parameters, only their values.
simin = setBlockParameter(simin,'vdp/Mu','Gain','[1 0 0 0]');
Of course, you have to make sure that the model will still work with that value for Gain.

Sounds like you have it sorted out. Good luck with your project.
