Summary of "Downloading and Installing Toolboxes in SCILAB[TUTORIAL]"

Main ideas / concepts

Scilab can be extended using “modules” / “toolboxes.”
- Toolboxes add extra functionality to Scilab that may not exist by default.
- Example use case: if Scilab can’t directly solve a specific type of equation (e.g., polynomial), you can install a toolbox designed for that task.
Modules/toolboxes are downloaded from the ADAMS repository.
- Repository URL mentioned: adams.scilab.org
- ADAMS full form: Automatic Modules Management for Scilab
- ADAMS is described as a package repository for Scilab extension modules/toolboxes.
Toolboxes are organized and searchable by categories.
- Example categories mentioned: Aerospace, bioinformatics, contributed, c/c binaries, etc.
- Example given: Data analysis and statistics → “Data handling” → CSV read/write toolbox.
Compatibility matters: check required Scilab version before installing.
- During the install process, the presenter emphasizes checking supported Scilab versions listed on the toolbox page.

Find the toolbox/module you want
- Go to: https://adams.scilab.org
- Browse categories or search for the toolbox.
- Optionally review the toolbox description and supported Scilab versions.
Download the toolbox file
- On the toolbox page, locate the toolbox/module file to download.
- Download it for your system.
- After download, note the local download path (the full path to the file/folder).
Install the toolbox in Scilab using ADAMS install
- In the Scilab console, run:
  - atoms install "<FULL_PATH_TO_TOOLBOX>"
- The path should be provided as a string.
- Expected behavior: Scilab connects to ADAMS to confirm availability/updates and then completes installation.
Confirm installation
- The console shows a success message once installation completes.
Load the toolbox into Scilab
- Use:
  - atoms load <toolbox_name>
- Important detail: the toolbox name to load is not necessarily the entire display title; it’s the specific name provided in the toolbox metadata/description or visible in console output/help.

Presenter’s demo toolbox: Equation Solver
- Toolbox name shown as: eqn_solver (displayed as “Eqn solver”)
Loading/using:
- atoms load eqn_solver
- Then the presenter uses:
  - help eqn_solver (or “help …” for quick-start documentation)
Functions included in the demo toolbox (4 total):
- B_solve
  - Finds roots using the bisection method.
- NR_solve
  - Finds roots using the Newton-Raphson method (referred to as Newton R method).
- quad_solver
  - Solves roots of a quadratic polynomial.
  - Input arguments: a, b, c
    - Interpreted as coefficients of:
      - ( x^2 \rightarrow a )
      - ( x \rightarrow b )
      - constant term (\rightarrow c)
  - Output: a matrix of roots (typically two roots for a quadratic).
  - Examples shown:
    - For (x^2 + 2x + 1) → roots -1 and -1
    - For (x^2 + x + 1) → roots are complex (two complex values with a plus/minus pattern)
- SC_solve
  - Finds a root using a method referred to as the “second method” (as stated in the video).

Automatic loading behavior
- The presenter states that after installing, Scilab can load the toolbox automatically (e.g., after restarting Scilab), reducing repeated manual loading.
Module Manager UI
- There is an icon/button for module manager inside Scilab.
- It can connect to the internet and show toolbox categories.
- From there, you can select a toolbox and click install.
Limitation of Module Manager vs website
- The presenter warns that the module manager UI does not show all toolboxes available on the ADAMS website.
- Reason given: not all toolboxes are packaged for the platforms supported by the module manager (example mentioned: Linux/Windows packaging).
- A toolbox created by the presenter was not packaged, so it didn’t appear in the module manager list, even though it exists on the website.

To extend Scilab:

Download toolboxes from ADAMS (website) or use the in-tool module manager
Install with atoms install
Load with atoms load to access new functions

Toolboxes add new computational capabilities (like equation/root solving) and allow those functions to be used like built-in Scilab functions.
