MATLAB: Unusual set_param error with system

errorset_paramsimulink

In the image I have attached, you can see if I type gcb, set_param works, but If I type in the exact same path, I get an error. Even in the error, its says:

 Invalid Simulink object name: R_edge_detect/Subsystem/Filt

This matches the object that is identified with the gcb command… Help!

Hi,

note, that there is a line break. This should work:

set_param(sprintf('R_edge_detect/Subsystem\n/Filt'), 'SampleTime', 'Ts')

Or: remove from the block the line break ;-).

Ok, found the answer and the trick is quite simple: thinking ;)

What about using a variable to save the first correct block path given by "gcb"? Nevertheless I wonder why

set_param([gcb '/xxx'], 'yyy')

changes the path to "current block/xxx".

My solution looks like the following now:

path = gcb
switch (get_param(gcb,'iso'))
  case 'mit Isolierung'
      set_param([path '/Isolierung'], 'BlockChoice', 'Schichtteil')
      set_param([path '/Isolierung1'], 'BlockChoice', 'Schichtteil')
      set_param([path '/Isolierung2'], 'BlockChoice', 'Schichtteil')
      set_param([path '/Isolierung3'], 'BlockChoice', 'Schichtteil')
      set_param([path '/Isolierung4'], 'BlockChoice', 'Schichtteil')
  case 'ohne Isolierung'
      set_param([path '/Isolierung'], 'BlockChoice', 'Bypass')
      set_param([path '/Isolierung1'], 'BlockChoice', 'Bypass')
      set_param([path '/Isolierung2'], 'BlockChoice', 'Bypass')
      set_param([path '/Isolierung3'], 'BlockChoice', 'Bypass')
      set_param([path '/Isolierung4'], 'BlockChoice', 'Bypass')
end

MATLAB: Set_param ‘Table’ datatype

Assuming mydata is a row vector, this should work:

assert(isrow(mydata), 'data is not row vector');
set_param(char(my_table), 'Table', ['[', num2str(mydata), ']']);

Note that depending on the values in mydata you may need to tweak the format string of num2str to get an accurate representation of the numbers as text.
