Solution Advantages of importing data files using uiimport command or selecting import data option in matlab file menu: It is used to import differenent types of ASCII data including data on the clipboard. This wizard helps the user by providing series of dialog boxes to provide the name of file,delimiters and set of variables we want to import. User friendly interface is provided to import files with required fields. Disadvantages: Matlab is an interpreted language, it can be slow, and poor programming practices can make it unacceptably slow. .
