Level-2 M-File S-Function - Use Level-2 M-file S-function in model

Library

User-Defined Functions

Description

This block allows you to use a Level-2 M-file S-function (see "Writing Level-2 M-File S-Functions") in a model. To do this, create an instance of this block in the model. Then enter the name of the Level-2 M-File S-function in the M-file name field of the block's parameter dialog box.

Note   Use the S-Function block to include a Level-1 M-file S-function in a block.

If the Level-2 M-file S-function defines any additional parameters, you can enter them in the Parameters field of the block's parameter dialog box. Enter them as MATLAB expressions that evaluate to their values in the order defined by the M-file S-function. Use commas to separate each expression.

If a model includes a Level-2 M-File S-Function block, and an error occurs in the S-function, the Level-2 M-File S-Function block displays M-file stack trace information for the error in a dialog box. Click OK to remove the dialog box.

Data Type Support

Depends on the M-file that defines the behavior of a particular instance of this block.

Parameters and Dialog Box

M-file name

Name of an M-file that defines the behavior of this block. The M-file must follow the Level-2 standard for writing M-file S-functions (see "Writing Level-2 M-File S-Functions").

Parameters

Values of the parameters of this block.
