Algorithm (Workflow)

This function, named matlabdir, is designed to return the default MATLAB directory used for custom toolboxes. It is part of the SolidGeometry library and was introduced in version 4.3. The function is specifically tailored for macOS systems.

Input Parameters

The function does not take any input parameters.

Output

• mldir: This is the output of the function, representing the default user MATLAB directory path.

Algorithm Explanation

The function begins by checking if the operating system is macOS using the ismac function. If the system is macOS, it proceeds with the following steps:

1. It calls the desktopdir function to obtain the current desktop directory path and stores it in the variable dd.
2. It uses the strfind function to locate all occurrences of the file separator character (denoted by filesep) within the dd string. The indices of these occurrences are stored in the variable k.
3. The function constructs the MATLAB directory path by concatenating the substring of dd up to the second-to-last file separator (using k(end-1)), followed by the string 'Documents/MATLAB/'. This constructed path is assigned to the output variable mldir.

Assumptions

• The function assumes it is being executed on a macOS system.
• The desktopdir function is assumed to return the correct desktop directory path.
• The directory structure follows the typical macOS user directory layout.
