Style in Matlab functions

What style is preferred in function variables? E.g.:

figure('WindowState','maximized') vs. figure('windowstate','maximized') vs. figure('WindowState','Maximized'); or find(xxx,1,'first') vs. find(xxx,1,'First') etc.

All the above works, but is any version more robust towards future Matalb updates?

Thank you.

I don't think that this will change in future updates, however, I think you can't go wrong with the styles that are used in the official documentations.

On the figure documentation website, there are some code examples:

figure('Name','Measured Data','NumberTitle','off');
set(groot,'DefaultFigureColormap','remove')

Theses examples look just like yours figure('WindowState','maximized').

Arguments have big letter at the end of each word and their values are lowercased (unless it's your own value like name).

However, I am not Mathworks employee and I do not have any information on this topic. This is something that just makes the most sense to me.

I use the upper/lower case of the default setting:

h = figure;
set(h)

The documentation explains, that the names and values are not case-sensitive, so it can be expected to be compatible with future versions also. Matlab is very stable in such documented details.

Using the dot notation requires the correct case for the names:

h.WindowState = 'normal';
% Error:
h.windowstate = 'normal';

Unrecognized property 'windowstate' for class 'matlab.ui.Figure'.
