Ha, I think we all have done things like that. Okay, instead of deleting why don't you edit the question to describe what you would like to happen rather than referencing MATLAB? The idea of an automatic x range is interesting, and as user1337's answer shows it's obviously been implemented for Wolfram|Alpha. I still think some nontrivial examples (with ranges manually selected) would strengthen the question.

I suggest that including code for your graphic may improve the speed and/or quality of the answers you receive.

comment How to do make Plot automatically figure out a domain interval?
No reading between the lines needed. I merely would like to see how MATLAB is handling some nontrivial examples as a reference for attempting to emulate its behavior. Also I would like to know what should be done for functions that cannot be symbolically analyzed. Should we evaluate an arbitrary range of x values and then attempt narrow the plot to an "interesting" part of the result?

An interesting question but could you provide additional examples? How are more complicated functions handled?

And you are running 10.1.0? (Referring to Why does list assignment with a packed array result in unpacked values?)

comment Efficiently test membership for a list of values
Could you give an example of the wildly varying results? I presume it's not simply packed vs. unpacked?

comment Is there a practical way to define a default value for missing keys in an Association?
@rcollyer You seem to be implying that Lookup doesn't already have this knitting but I believe it does; it is not relying on Missing to detect a missing value. I believe it finds it directly. I mean that Lookup is not doing something like /. _Missing -> 0 in my second example. What therefore is the complication?
