How do I changing file name in a "To File" block in Simulink from matlab command window?

Hi, Is there a way that i can change the file name in a "To File" block in Simulink from Matlab?

To change a variable in a "Constant" block the following line works.

set_param('model/Constant1','Value','5')

However changing the file name in a "To File" block using the same approach results in an error: "Invalid Simulink object specifier"

The input I have used is:

set_param('model/To File','FileName','test.mat')

Any solutions to this problem would be appreciated, as well as more efficient alternatives to use.

I'm running Matlab R2013b.

You can use gcb to get the current block:

set_param(gcb,'filename','hello_world.mat')

And to see the name of the block:

'amodel/To File'

Works perfectly, Thanks!
