回答： Rodger Herbst 2020-4-1

when copying text into command window, it treats the ' symbol as an apostrophe, and gives an error. As the image below shows, when I go in and replace the slanted apostrophe with the ' on the command line, the code works fine. how can I get the command window to see the ' the first time instead of the slanted symbol? I have Matlab win10, not Matlab mobile, so I can't access any iSO to fix it.

"But in my problem statement I noted that I also tried copying directly from aski text, and the problem persists."

I very much doubt that. The ASCII character set includes

' apostrophe char(39)
` grave accent char(96)

but does NOT include a right single quote. For that you will need some other character encoding, e.g. Unicode:

’ RIGHT SINGLE QUOTATION MARK (U+2019)
‘ LEFT SINGLE QUOTATION MARK (U+2018) (here just for completeness)

Because no common keyboard layout includes a "right single quote" key, this character is almost always included in text as a result of an application converting the apostrophe character via a "Smart Quotes" feature.

Quite a number of years ago, one of the document editors I used (in the sense of a program that you would use to write a book complete with multiple columns, illustrations, and so on), the program treated the ' character as inputing ʼ unless you specifically used a sequence to change that. It was not a smart quotes feature, it was more a key mapping, because for manuscript purposes ʼ for contractions is more common than '
