Create a Simulink model with script

Hi, the basics of creating a Simulink model with scripts is clear when the mathworks is checked, my question is about to change the pamameters of a added block. E.g. to add a sin block

   add_block('built-in/Sin', [gcs,'/Uref2'],...
    'Position', [140 95 170 125],...
    'SampleTime','0');

But how can I change amplitude and frequency also other parameters of the sin block, thanx for any comment in advance

Use

block = add_block(...);

to get the block handle. Set parameters using

set_param(block,param,value)

Where

param

is a string containing the parameter name, e.g. 'Amplitude' and

value

is the value the parameter should get (also a string!), e.g. '5'.

You can also set the parameters directly in the add_block(...,'Amplitude','5') command.

Search for "sine wave function" on this page for all possible parameters.

I want to learn also how can I change any parameters of any block in Simulink, I mean how can I find the exact names of the parameters that belongs to any specific block in Simulink. E.g. to change number of inputs of a Mux block, or appearance as well. I have tried with

add_block('built-in/Mux', [gcs,'/Mux1'],...
  'NumberofInputs','3','Position',pos);

but it doesn't work, what is the general way to find put all specific parameter names of a block to change with script, thanks a lot in advance

See http://mathworks.com/help/simulink/slref/get_param.html for info on how to get all block parameters of a block using

get_param

You can then set them using

set_param

again.

add_block('built-in/Mux', [gcs,'/Mux1'],'Inputs','10','DisplayOption','bar');

The parameters are 'Inputs' 'DisplayOption'

With Below mentioned code also you can add, set and get the newly added block details:

SimSubsystemObj = get_param(add_block(fullBlkSrcPath,[destinationpath,'/',blockname],... 'Position',[LeftPost BottomPos Width Height]),'Object'); %For Creating the Block and getting its handler%

set_param(SimSubsystemObj,'SampleTime','-1'); %For Setting block Value%
