Requires uihtml an additional toolbox?

Hey guys,

do I need an additional toolbox to use the uihtml function or is it already integrated into the 2021b version?

Thanks a lot!

Kindest regards,

Jan

uihtml belongs to the standard toolboxes of Matlab. So you do not need a toolbox for this.

Ok, thank you.

FYI one way you can determine this is by looking at the left side of the documentation page. For uihtml the "breadcrumbs" below the Contents and Documentation Home headers start off with MATLAB. That means the function is part of MATLAB. [The note at the end of the documentation page telling you in which release a function was introduced can also be helpful if you're trying to determine what configuration you'll need to have in order to use the function.]

Compare this with, for example, fmincon. The start of the breadcrumbs is Optimization Toolbox, and indeed that toolbox is where that function lives.

Sometimes this can break down especially if a function is overloaded for different types of objects in different toolboxes. One example of this is tf, which you can see from the documentation search has pages in both Control System Toolbox and Signal Processing Toolbox. The one in Signal Processing Toolbox constructs the numerator and denominator coefficient vectors for a digitalFilter object.

Thanks, Steven, for this useful addition.

It took me some time and finally a discussion in the forum to find out that this detail is reliable. It would be an enhancement, if the required toolbox is marked more prominently like: "Part of the Image Processing Toolbox".

[Steven Lord]

That's a reasonable suggestion. If that information were marked more prominently on the documentation page, where would you look first for it?

• As a section at the same level as Syntax, Description, Examples, etc.? Maybe a "Product" section?
• Down at the end of the page with the "Introduced in/before" information (which could be useful if the function has moved between toolboxes during its lifetime)?
• Somewhere else (where and what would lead you to expect that information to be in that location)?

@Steven Lord: The location is fine already, but a newcomer needs a hint, that the topmost element of the list is the toolbox. Maybe just a hint and an additional horizontal line:

If a command exists in several toolboxes, a list might appear behind the keyword "Toolbox" and maybe the currently focussed toolbox is highlighted, e.g. bold.

It would be better to post this as enhancement request than as comment in the forum. Should I do this or do you have a shortcut to forward this idea to the web designers?

Thanks a lot Steven, that infromation is very useful!
