Algorithm (Workflow)

This function, smbCreateBlockConst, is designed to create a Simulink block with a constant value. It is part of the SG-Library and was introduced in SolidGeometry 3.3. The function takes up to three input parameters:

• SName: The name of the generator block. The default value is 'Const'.
• EPort: An optional port to connect. If not provided, it defaults to an empty string.
• amp: An optional amplitude value for the constant block. The default value is 1.

The function begins by checking the number of input arguments (nargin) and assigns default values if necessary. It then proceeds with the following steps:

1. Calls smbAddBlock to add a 'Constant' block to the current Simulink model (gcs) with the specified SName.
2. Sets the position of the newly added block using smbSetPosition and smbNewGridPos with a grid position of -1.
3. Sets the 'Value' parameter of the block to the specified amp using set_param.
4. If EPort is not empty, it performs the following:
• Finds the subname by extracting the portion of EPort before the last '/' character.
• Uses smbWhich to resolve the subname.
• Calls smbGetPorts to retrieve port information for the subname.
• If there are existing connections, it deletes them using delete_line.
• Adds a new line connecting the constant block to the specified EPort using add_line with 'autorouting' enabled.

This function is useful for creating and connecting constant blocks in a Simulink model, with optional customization of the block name, connection port, and amplitude value.
