Algorithm (Workflow)

This function, lastuidir, is designed to retrieve the file path, file name, and file extension of the last file opened in the MATLAB editor using the uiopen function. It is part of the SolidGeometry library and was introduced in version 5.0.

Input Parameters

The function does not take any input parameters. It operates based on the internal state of the MATLAB environment, specifically the history of files opened using uiopen.

Output Parameters

fp: The file path including the file separator at the end.
fn: The file name without the path or extension.
fe: The file extension.

Algorithm Steps

The function calls HxSearch with the string 'uiopen(' to search for occurrences of files opened using uiopen. The search is limited to the most recent occurrence by specifying the last parameter as 1.
If multiple results are found, the function selects the last entry using text(end,:).
The function locates the position in the string where the file path starts by searching for 'uiopen('' and adjusts the index accordingly.
It then extracts the substring containing the file path and name by finding the position of the closing '' before ',1)'.
The fileparts function is used to split the extracted string into the file path, name, and extension.
The file path is concatenated with the file separator to ensure it ends with a separator.
