Variable Names

Create valid variable names and avoid potential naming conflicts.

Base and Function Workspaces

The base workspace stores variables that you create at the command line or that a script creates when you run it from the command line or Editor. To protect the integrity of the data, every function has its own workspace that is separate from the base workspace and all other workspaces.

Check Variable Scope in Editor

Use MATLAB® function and variable highlighting features to identify when and where your code uses a particular function or variable.
