Using set_param for multiple variables.

I am trying to update 20 variables in a Simulink model by using set_param in an m script file. Is there any way to do this using a "for i=1:20" subroutine referencing Constant1, Constant2, Constant3, etc, as Constant(i) and with data from Q(i), so I do not have to write 20 separate entries in the set_param command?

Sure. sprintf is handy here.

for idx = 1:20
  blockName = sprintf('myModel/Constant%i',idx);
  blockValue = sprintf('Q(%i)',idx);
  set_param(blockName,'Value',blockValue);
end

You can also use the num2str function if that works better.

set_param(blockName,'Value',num2str(Q(idx));
