Why Use Relative Paths?

If you specify paths and files with absolute paths and later move them, you must change these paths to point to new locations. To avoid this problem, use relative paths for custom code options that specify paths or files.

Searching Relative Paths

Search paths exist relative to these folders:

• The current folder

• The model folder (if different from the current folder)

• The custom list of folders that you specify

• All the folders on the MATLAB search path, excluding the toolbox folders

Path Syntax Rules

When you construct relative paths for custom code, follow these syntax rules:

• You can use the forward slash (/) or backward slash (\) as a file separator, regardless of whether you are on a UNIX or PC platform. The makefile generator parses these strings and returns the path names with the correct platform-specific file separators.

• You can use tokens that evaluate in the MATLAB workspace, if you enclose them with dollar signs ($...$). For example, consider this path:

  $mydir1$\dir1

  In this example, mydir1 is a string variable that you define in the MATLAB workspace as 'd:\work\source\module1'. In the generated code, this custom include path appears as:

  d:\work\source\module1\dir1

• You must enclose paths in double quotes if they contain spaces or other nonstandard path characters, such as hyphens (-).
