Get environment variable in MATLAB Last Updated : 06 Jul, 2021 Comments Improve Suggest changes Like Article Like Report In this article, we are going to discuss "Getting environment variable", which can be done using getenv() function. The getenv() function is used to get the operating system environment variable. Syntax:value = getenv(name) Parameters: This function accepts a parameter name parameter. name: This is the specified name for which environmental variable is going to be searched. Return Value: It returns the operating system environment variable. Example 1 Matlab % MATLAB code for Environment Variable GFG % has been created and later replaced with "C:\GFG" variable % Calling the setenv() function % to replace the "GFG" name % with value "C:\GFG" setenv('GFG','C:\GFG'); % Calling the getenv() function to % Get the current environment variable name getenv('GFG') Output ans = C:\GFG Here the getenv() function returns the current environmental variable name "C:\GFG". Example 2 Matlab % MATLAB code for Calling the setenv() % to set the value % "D:\geeksforgeeks\gfg" over % the variable "a" setenv('a','D:\geeksforgeeks\gfg'); % Calling the getenv() function to % Get the current environment variable name getenv('a') Output ans = D:\geeksforgeeks\gfg Comment More infoAdvertise with us Next Article Get environment variable in MATLAB K Kanchan_Ray Follow Improve Article Tags : Software Engineering MATLAB Similar Reads Set environment variable in MATLAB Setting environment variables with the help of setenv() function. The setenv() function is used to set the specified value of an operating system environment variable. Here the environment variable "name" will be replaced with "value", where "name" and "value" is its parameters.

But before going to that, let's first understand what exactly is MATLAB and its environment. MATLAB is a programming language, which is specially designed 4 min read Global Variables in MATLAB Variables in programming are generally storage spaces to store a certain type of data. There are many types of variables, but two commonly used types are local and Global variables. Generally, each MATLAB function has its own local variables. But sometimes for the sake of programming, we need to cha 4 min read Clear variable from Memory in MATLAB Clearing variables from memory, with the help of clearvars operation. The clearvars operation is used to clear the specified variables from memory or from the currently active workspace. Syntax:clearvars variables clearvars -except keepVariables Parameters: This function accepts a parameter. variabl 1 min read Variable Names in MATLAB A variable is a named-memory location that stores different types of data which can be used to perform a specific set of operations. It can be thought of as a container that holds some value in memory. The Matlab workspace store all the variables being used during a session. This workspace not only 5 min read Private Functions in MATLAB Private functions are useful when you want to limit the scope of a function. Here we will learn how to create private functions and also use them. Private functions are primary functions that are visible only to a limited group of other functions. Generally, we make private functions, if we want to 2 min read MATLAB - Variables Prerequisite: Getting Started with MATLAB A variable in simple terms is a storage place that has some memory allocated to it. Basically, a variable used to store some form of data. Different types of variables require different amounts of memory and have some specific set of operations that can be a 3 min read Set Variable Data Types in MATLAB There are many cases when a user has to import data into MATLAB script from various files. These file types could be .txt, .xlsx, .csv, .dat, etc. types. Now, each file type has its own method of defining data types. However, for computation purposes, MATLAB requires the data to be of numeric type, 3 min read Void Function in MATLAB When defining void* output in the library definition file, MATLAB specifies that the argument MLTYPE must be one of these: a typedef from the library. Use only to produce scalar data. If the library has a typedef defined for void* that uses that name, MATLAB specifies MLTYPE as the new type name in 2 min read Data Type Conversion in MATLAB Data Types in MATLAB is the upheld information organizes that are utilized for calculation.
