Thread Subject: How to programatically refresh a Simulink model?

Hello people,

I wonder if there's a way to programatically refresh a
simulink model, i.e. do the same as the "Refresh Model
blocks" button does when clicked, but programatically.

I'm having a real wierd problem with buses. When I open my
model, if I press the "Start Simulation" button, it works
perfectly, although, if I open the model and press the
"Update Diagram", simulink generates an error when I try to
extract the 'InputSignals' parameter from a bus selector.

I ask about the "Refresh Model blocks" because if I open the
model, press "Refresh Model blocks" then "Update Diagram",
it also works!

in resume:

Open -> Play => OK
Open -> Refresh -> Update Diagram => OK
Open -> Update Diagram => *Error*

Thx in advance.

Hi Paulo,
Try this:
h = get_param(bdroot,'object')
h.refreshModelBlocks

char(filter(1,[1,-1],[105 zq])), clear zq

Thanks! It worked beautifully.
