setting the "hold" property for axes

the suggested way to set hold to "on" "all" oder "off" seems to be writing
To set most other properties, a syntax like
txt=xlabel(t,'My_Xlabel'); txt.FontSize = 18; txt.FontWeight = 'bold';
seems to be suggested.
Is there a way to apply this syntax to the hold property of the axes ?
A code like
which was intuitive to me, doesn't work.

The hold function corresponds to the NextPlot property on the Axes.
I realize that's a little confusing - hold has only two states, on or off, but NextPlot has a few more options. All the way at the bottom of the hold documentation page you'll find this text:
The hold function sets these properties:
So the code snippet you're looking for is:
ax.NextPlot = 'add';
There's a small caveat not mentioned in the documentation above, which is that hold off has some slightly different behavior with uiaxes. Instead of setting the NextPlot property to 'replace' it sets it to 'replacechildren'. This can be more useful in apps - it means that the children of the axes will be replaced but the axes will retain other settings. Details about all the different kinds of NextPlot on figure and axes are here:
