getenv

Environment variable

Syntax

val = getenv(name)

Description

val = getenv(name) returns the value of the operating system environment variable name as a character vector. If name does not exist, then getenv returns an empty character vector.

On UNIX^® platforms, the shell you use to start MATLAB^® determines the operating system environment. For example, on a Mac platform, starting MATLAB from the Applications folder creates an environment that is different from that created by starting MATLAB from Terminal.

Examples

Display System Root Directory on Windows

res = getenv("SYSTEMROOT")

res = 'C:\windows'
