How to Specify a Path for a Simulink Object

Many of the commands described in this chapter require that you identify a Simulink system or block. Identify systems and blocks by specifying their paths:

To identify a system, specify its name, which is the name of the file that contains the system description, without the mdl extension.

system

To identify a subsystem, specify the system and the hierarchy of subsystems in which the subsystem resides.

system/subsystem₁/.../subsystem

To identify a block, specify the path of the system that contains the block and specify the block name.

system/subsystem₁/.../subsystem/block

If the block name includes a newline or carriage return, specify the block name as a string vector and use sprintf('\n') as the newline character. For example, these lines assign the newline character to cr, then get the value for the Signal Generator block's Amplitude parameter.

cr = sprintf('\n');
get_param(['untitled/Signal',cr,'Generator'],'Amplitude')
ans =
   1

If the block name includes a slash character (/), you repeat the slash when you specify the block name. For example, to get the value of the Location parameter for the block named Signal/Noise in the mymodel system.

get_param('mymodel/Signal//Noise','Location')
