Algorithm (Workflow)

This function, smlDeleteall, is designed to delete all lines and blocks from a specified block diagram in MATLAB. It is part of the SolidGeometry library and was introduced in version 4.7.

Input Parameters

• asys: The system from which lines or blocks are to be deleted. The default value is the current system, obtained using gcs (get current system).
• typ: Specifies the type of elements to delete. It can be either 'line', 'block', or both. The default value is {'line','block'}.

Algorithm Steps

1. The function begins by retrieving the input parameters using the helper function getfuncparams. If no parameters are provided, it defaults to the current system and both 'line' and 'block' types.
2. It checks if the typ parameter is a cell array. If it is, the function iterates over each element in the array, recursively calling smlDeleteall for each type specified.
3. If typ is not a cell array, the function uses find_system to locate all elements of the specified type within the system asys. The 'FindAll','on' options ensure that all matching elements are found.
4. Once the elements are identified, the function deletes them using the delete command.

Example Usage

The example provided in the code demonstrates how to use the function:

new_system('SGLib_Arduino_Example','FromFile','Example_Arduino.slx'); 
open_system('SGLib_Arduino_Example');
smlDeleteall(gcs,'line')

This example creates a new system from a file, opens it, and then deletes all lines from the current system.
