Do Level-1 MATLAB S-Functions support bus inputs?

Best Answer

Neither Level-1 nor Level-2 MATLAB S-Functions support bus inputs. The workarounds are

(a) Concatenate the multiple inputs into an array if they are of the same data type

(b) Use multiple input arguments (in the case of a Level-2 S-Function)

If using a Level-1 S-Function, it is highly recommended that it be upgraded to a Level-2 S-Function.

Since Level-1 MATLAB S-functions only have one input, you'll need to concatenate A and B to supply them as the input. Your indexing will depend on how you concatenate them before supplying them to the S-function.

Also, may I recommend that you try and switch to using Level-2 MATLAB S-functions? Level-1 S-functions have been deprecated for a long time, and have very limited features. Please see Convert Level-1 MATLAB S-Functions to Level-2.

MATLAB: Do I get an error while using a Fortran Level-1 S-function inside a triggered subsystem in Simulink 7.4 (R2009b)

This is expected behavior. This issue occurs because triggered subsystems do not support continuous sample times, but Fortran Level-1 S-functions support only continuous sample times. Therefore Fortran Level-1 S-functions can not be included inside a triggered subsystem.

There are two ways to work around this issue:

1. Use Level-2 S-functions instead of Level-1 S-functions as explained in the following documentation page:

 <http://www.mathworks.com/access/helpdesk/help/toolbox/simulink/sfg/f5-88442.html>

2. Use enabled subsystems in place of triggered subsystems. This is demonstrated in the attached model "Mathworks_Test_Works.mdl"
