Algorithm (Workflow)

This algorithm is a MATLAB function named openinmatlabeditor that is designed to open a specified file in the MATLAB editor. If the file does not exist, it creates the file. The function is part of the SolidGeometry library and was introduced in version 5.0.

Input Parameters

fname: The name of the file to be opened or created. It is a string representing the file name.
ln: (Optional) The line number where the cursor should be placed in the file. This is passed as a variable argument.

Algorithm Steps

The function begins by calling getfuncparams to retrieve the line number ln from the variable arguments. If no line number is provided, it defaults to 1.
It uses the which function to determine the full path of the file specified by fname.
If the file path pname is empty, it checks if the file exists using exist(fname).
If the file does not exist (i.e., exist(fname)~=2), it creates the file using fopen with write permissions and US-ASCII encoding, then immediately closes it with fclose.
If the file exists, it calls opentolineTL with the file name and line number to open the file at the specified line.
If the file path pname is not empty, it calls opentolineTL with the full path and line number to open the file at the specified line.

The function ensures that the specified file is opened in the MATLAB editor, creating it if necessary, and positions the cursor at the desired line.
