Output Ports Pane

The Output Ports pane allows you to inspect and modify the properties of the S-function's output ports.

The pane comprises an editable table that lists the properties of the output ports in the order in which the ports appear on the S-function block. Each row of the table corresponds to a port. Each entry in the row displays a property of the port as follows.

Port name

Name of the port. Edit this field to change the port name.

Dimensions

Lists the number of dimensions of signals output by the port. To display a list of supported dimensions, click the adjacent button. To change the port's dimensionality, select a new value from the list. (Simulink signals can have at most two dimensions).

Row

Specifies the size of the output signal's first (or only) dimension.

Column

Specifies the size of the output signal's second dimension (only if the output port accepts 2-D signals).

Complexity

Specifies whether the port outputs real or complex-valued signals.

Frame

Specifies whether this port accepts frame-based signals generated by the Communications Blockset. See the documentation for this blockset for more information.
