variableNames

Names of variables in workspace

Since R2025a

Syntax

s = variableNames(w)

s = variableNames(w,var1,...,varN)

Description

s = variableNames(w) returns the names of the variables contained in the specified workspace object.

s = variableNames(w,var1,...,varN) returns the names of the specified variables. If any of the specified variables do not exist in w, they are omitted from the output.

Examples

Return Variable Names

Create a set of variables in the base workspace.

a = 1;
b = true;
c = "Hello, World";

Create a workspace object for the base workspace. Then return the variable names using the workspace object.

w = matlab.lang.Workspace.baseWorkspace;
s = variableNames(w)

s = 3×1 string
    "a"
    "b"
    "c"

Return Specified Variable Names

Create a set of variables in the base workspace.

a = 1;
b = true;
c = "Hello, World";

Create a workspace object for the base workspace. Then return the variable names a and b.

w = matlab.lang.Workspace.baseWorkspace;
s = variableNames(w,"a","b")

s = 2×1 string
    "a"
    "b"

Input Arguments

w — Workspace

matlab.lang.Workspace object

var1,...,varN — Variables (as separate arguments)

string scalars | character vectors

Variables, specified as string scalars or character vectors.

Output Arguments

s — Names of variables

string array

Names of the variables, returned as a string array.
