Here's the question I got from lecture,
Find the help pages for num2str and disp.
Given >>speedlimit = 5;
Write a line of code that displays the message “The local speed limit is speedlimit km/h”, inserting the value where indicated.
How can I display those line only using num2str and disp command?
