MATLAB: Can I change the name of a parameter of a existing simulink block

blocknameparametersimulink

Hello,

I want to change the name of a/the parameter of a PS Constant block. I want to change it from 'constant' to 'constant1'.

Is this possible?

When I go to the Mask-Parameters I cant adjust anything because it is read only. Can I maybe make my own block, copy all properties of the PS Constant block into it and only change the parameter name?

Thanks in advance!

Greetings Boudewijn

You can't change the name of the parameter, but you can add another mask on top of the block and create a new set of parameters that map to the ones on the mask below. (In newer releases, this mapping can be done automatically by promoting block parameters to a mask)

If you want to get the real parameters name of your block, type in windows command:

get_param('ModelName/AWGN Channel1','dialogparameters')

MATLAB: How to change the value of a Constant block programmatically during a simulation

You can change the value of a Constant block programmatically as follows:

% Find all blocks of type 'Constant', with the name 'Constant1'.
foundBlock = find_system(gcb, 'BlockType', 'Constant', 'Name', 'Constant1');
% List the possible parameters for the found block. This step is only done to
% identify the name of the parameter that needs to be changed when you don't
% know for sure what the correct spelling might be.
% foundBlock is a cell array.
objParams = get_param(foundBlock{1}, 'ObjectParameters')
% After identifying the parameter 'Value', proceed to change it.
set_param(foundBlock{1}, 'Value', '8')
