Installation

The toolbox is published in two forms. You need one of them, not both.

• The installer, MTI-Toolbox-<version>.mltbx — the normal case. MATLAB installs it as an add-on, sets your path for you, and registers the documentation with the MATLAB Help browser.
• The source archive, MTI-Toolbox-<version>-source.zip — for when your environment restricts add-ons, or you would rather not run an installer. You put the files on the path yourself, and read the manual that comes in the folder instead of the Help browser.

Both forms carry the same toolbox: the same source, the same demos, the same bundled third-party kit and the same offline HTML documentation. The build compares the two against each other file by file, so neither can quietly ship something the other does not.

Note: Nothing is downloaded while you install

Neither form fetches anything. Everything the toolbox needs from outside MathWorks — that is, the Sparse Grids MATLAB Kit — is already inside the file you downloaded, so installation works offline and cannot fail because a download did.

Before you start

Read Requirements and check the product tables against your licence. Nothing here enforces them: both routes install perfectly happily without the Optimization Toolbox, and you find out when the toolbox will not run. The environment check named in both routes below is what turns that into an answer you get on purpose.

Route 1 — the installer

1. Install the package

Download MTI-Toolbox-<version>.mltbx and either double-click it in MATLAB’s Current Folder browser, which opens MATLAB’s add-on installer, or install it from the Command Window:

matlab.addons.install("MTI-Toolbox-3.0.0.mltbx")

That is the whole installation. MATLAB unpacks the toolbox into its add-ons folder and puts src/, demo/, externalTools/ and doc/ on your MATLAB path, with their subfolders — you do not run addpath, and you do not need to save the path.

2. Check your environment

Run this before anything else:

environmentChecker

It reports every product and package the toolbox depends on, says whether each one is available to you, and — when one is not — what to do about it. For a MathWorks product it separates not installed from installed but no licence available, because only the second one is your licence administrator’s problem. See environmentChecker.

3. Read the documentation in the Help browser

The installer registers the toolbox documentation with MATLAB, so the pages you are reading now are available offline inside MATLAB, under Supplemental Software in the Help browser. Every documented function also carries a Documentation: link at the end of its help text that opens its page there.

Then try a demo — every entry in the demo catalogue has a one-line openDemo command you can copy into the Command Window.

Removing it again

Uninstall it the way you would any add-on: on the Home tab, open Add-Ons, then Manage Add-Ons, and remove MTI-Toolbox. From the Command Window, matlab.addons.installedAddons lists what is installed and matlab.addons.uninstall takes it away.

Route 2 — the source archive

1. Unpack it somewhere permanent

Download MTI-Toolbox-<version>-source.zip and unzip it. It unpacks to a single folder named for the release, MTI-Toolbox-<version>/, so it cannot scatter itself over whatever directory you unzipped in.

Move that folder to where you want to keep it before the next step. The path entry you are about to add points at wherever the folder is, so unpacking into a downloads directory and adding it from there is a surprise you meet later.

2. Put it on the MATLAB path

Point these two lines at wherever you put the folder:

addpath(genpath("C:\Toolboxes\MTI-Toolbox-3.0.0"))
savepath

genpath gives you the same set of folders the installer would have added. savepath makes it survive a restart.

Warning: If savepath cannot write

savepath needs permission to write MATLAB’s path file, and a locked-down installation — quite possibly the reason you are on this route — may not give it. Put the addpath line in your startup.m instead; it then runs at every MATLAB start.

3. Check your environment

Run this before anything else:

environmentChecker

It reports every product and package the toolbox depends on, says whether each one is available to you, and — when one is not — what to do about it. On this route it also confirms the path step above worked, since it can only run once src/ is on the path. See environmentChecker.

4. Read the documentation from the folder

This route gets no Help-browser integration. Nothing registers the pages with MATLAB, so they do not appear under Supplemental Software, and doc will not find them. That is expected rather than a failed installation — and it is why the archive carries its own documentation:

• MTI-Toolbox-Manual-<version>.pdf, in the folder you unpacked. The complete documentation as one printable manual.
• doc/html/, the same pages as HTML, for reading in a browser. Each function’s Documentation: help link opens its page from here, in MATLAB’s browser, exactly as on the other route.
• index.md, the documentation landing page, as the short orientation.

Then try a demo — every entry in the demo catalogue has a one-line openDemo command you can copy into the Command Window.

Removing it again

rmpath(genpath(...)) on the same folder you added, then savepath, then delete the folder. Nothing was installed anywhere else.

The Sparse Grids MATLAB Kit comes with it

One capability — multilinearizing a Simulink model with mlinearize — needs a third-party package, the Sparse Grids MATLAB Kit. You do not have to obtain it: it ships inside both forms, in its own folder under externalTools/, so a normal installation puts it on your path with everything else.

It stays listed as a gated capability on the Requirements page regardless, because shipping a package says how it reaches you, not whether the toolbox needs it — and an installed copy can still be deleted. That is one of the things environmentChecker looks for.
