MATLAB language server

MATLAB® language server implements the Microsoft® Language Server Protocol for the MATLAB language.

MATLAB language server requires MATLAB version R2021a or later.

Note: This language server will no longer support MATLAB R2021a in a future release. To use advanced features or run MATLAB code, you will need to have MATLAB R2021b or later installed.

Features Implemented

MATLAB language server implements several Language Server Protocol features and their related services:

• Code diagnostics — publishDiagnostics
• Quick fixes — codeActionProvider
• Document formatting — documentFormattingProvider
• Code completions — completionProvider
• Function signature help — signatureHelpProvider
• Go to definition — definitionProvider
• Go to references — referencesProvider
• Document symbols — documentSymbol
• Symbol rename - renameProvider

Clients

MATLAB language server supports these editors by installing the corresponding extension:

• Neovim — nvim-lspconfig
• Visual Studio® Code — MATLAB extension for Visual Studio Code
