Algorithm (Workflow)

This function, smbAddLine, is part of the SimMechanics library and is used to create a line between two block ports in a Simulink model. The function is designed to work within the context of a Simulink model, specifically using the current system as the target for adding the line.

Input Parameters

• P1: This is the name of the first port. It is a string that specifies the port on the first block to which the line will be connected.
• P2: This is the name of the second port. It is a string that specifies the port on the second block to which the line will be connected.

Output Results

• h: This is the handle to the line that is created. It is returned by the function and can be used for further manipulation or querying of the line within the Simulink model.

Function Workflow

The function begins by determining the current system in Simulink using the gcs function, which stands for "get current system." This function returns the name of the currently active Simulink system, which is stored in the variable FSys.

Next, the function calls add_line, a built-in Simulink function, with three arguments: FSys, P1, and P2. The add_line function creates a line between the specified ports P1 and P2 within the current system FSys.

The handle to the newly created line is returned as the output h.

Example Usage

The example provided in the comments demonstrates how to use the function to create lines between ports of different frames:

smbAddFrame('Frame 1');
smbAddFrame('Frame 2');
smbAddFrame('Frame 3');
smbAddLine('Frame 1/LConn1', 'Frame 2/Rconn1');
smbAddLine('Frame 1/LConn1', 'Frame 3/Rconn1');

In this example, three frames are created, and lines are drawn between the specified ports of these frames.
