📄 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.
