Variabili di ambito e generazione dei nomi

Condividere dati tra funzioni o workspace, generare nomi validi di variabili

Ciascuna funzione ha un proprio workspace, separato dal workspace di base riservato agli script e alla riga di comando. Per i modi preferiti di passare i dati tra le funzioni, vedere Share Data Between Workspaces.

Argomenti

  • 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.

  • Variable Names

    Create valid variable names and avoid potential naming conflicts.

  • Transparency in MATLAB Code

    Write code that MATLAB can optimize more effectively.

Resolve Error: Attempt to Add Variable to a Static Workspace.

Troubleshoot errors when attempting to add variables to nested and anonymous functions. Variables used within nested and anonymous functions must be present in the text of the code. If you add a variable to the workspace of an anonymous function, a nested function, or a function that contains a nested function dynamically, MATLAB issues an error.
