Use of assignment '=' in plot command?

Hi

There is a lot of ways to ask this question and it is maybe more of a discussion topic, but with ~10 years of medium MATLAB use I got a bit confused by this way of calling plot so I ask:

Should this code run/work?

y=1:10;
plot(y,'.-',linewidth=2)

Or maybe I just missed some release notes explaining this?

That name-value sytnax was introduced in R2021a:

y=1:10;
plot(y,'.-',linewidth=2)
%           ^^^^^^^^^^^ this syntax introduced R2021a

"Or maybe I just missed some release notes explaining this?"

The new syntax is explained in the MATLAB documentation, MATLAB blogs, and Release Notes:

Before R2021a you will have to use the old approach (which of course still works in the newer versions):

plot(y,'.-','linewidth',2)
