Limitations

This package has some constraints and limitations:

  • Notebooks running on the same server share the same MATLAB process and workspace. It is currently not possible to have separate workspaces for each notebook.

  • Kernels cannot restart MATLAB automatically when users explicitly terminate their MATLAB session using the exit command or through the browser-based MATLAB development environment. Users must manually restart MATLAB using the options shown here.

  • The package does not support executing some MATLAB commands in notebooks. These include:

    • Commands that request input from users. For example: input and keyboard.

    • MATLAB debugging commands. For example: dbstep, dbup, and dbstack.

    • Commands that open another browser tab. For example: doc and appdesigner.

    • Commands that create animations. For example: movie.

    • For MATLAB R2022a and earlier, lasterr and lasterror do not capture MATLAB errors from execution in notebooks.

  • Notebook results are truncated when there are more than 10 rows or 30 columns of results from MATLAB. This is represented by a ... at the end of the result. For example:

    truncation-issue

  • Handles for graphics objects are scoped to a single cell in MATLAB versions <= R2023a. For example:

    invalid-handle

  • Graphics functions like gca, gcf, gco, gcbo, gcbf, clf, cla, which access current handles, are scoped to a single notebook cell in MATLAB versions <= R2023a. The following example illustrates this:

    gca-issue

  • Notebooks do not show intermediate figures that were created during execution.

  • Outputs from code cells are only displayed after the entire code cell has been run.

  • MATLAB notebooks and MATLAB files do not autoindent after case statements.

  • For MATLAB R2024a and later, tables are displayed as ASCII instead of HTML if the table meets any of the below conditions. Note that the below list is not exhaustive.

    • is an empty table
    • has more than 1000 rows
    • has more than 100 columns
    • has nested/grouped headers
    • has multi-column variables
    • is an event table
    • is a dataset
