Hi,
I am trying to cchange the initial condition of an integrator in Simulink by using Matlab code. I am using the following lines:
init_cond_integrator=[pi/3;0];
set_param('ClosedLoop_PID_MRFT_with_actuator/Manipulator Dynamics/Integrator1','InitialCondition',num2str(init_cond_integrator));
It gives the following error:
'ClosedLoop_PID_MRFT_with_actuator/Manipulator Dynamics/Integrator1' has unapplied changes. Please apply or cancel these changes before running the simulation.
Any help will be highly appreciated.
Thanks!

The error message says you have the dialog window open and changes have not been applied. Click apply or Ok and then proceed.

Yes, right, but that seems undoable using the set_param command.

set_param(Block,'InitialCondition',mat2str([1,2]))
