getenv

Get the value of an environment variable.

Syntax

• s = getenv(env_name)

Input argument

• env_name - string scalar, character vector, string array, cell array of character vectors: environment variable name.

Output argument

• s - string scalar, character vector, string array, cell array of character vectors: the environment variable value.

Description

getenv returns the value of an environment variable if it exists.

If the environment variable does not exist, it will return ''.

If env_name is a nonscalar cell array of character vectors or string array, then val has the same dimensions and type as env_name.

If env_name is a string scalar, then s is a character vector.

Example

getenv('OS')
getenv('myenvvar')
getenv(["PATH"; "OS"])
getenv({'PATH'; 'OS'})
