Dear Experts,

Just wondering if there is a simple way to change sampling rate of multiple blocks?

Or if there is a programmatic way of list out all blocks inside a model, and use list assignment to change sampling rate?

Please comment,

Thanks,

Please see the functions find_system to list blocks within your model. You will need to know the name of the parameter for sample time, but for built-in blocks, it is SampleTime. You can then set

set_param(gcb, 'SampleTime', '0.001')

for each block.

ts=0.0001 % your sample time
s=find_system('untitled')
for k=2:numel(s)
  m=s{k}
  try
      b=get_param(m,'sample time');
      set_param(m,'sample time',num2str(ts))
  catch
  end
