This is for Matlab

Prompt the user to input an integer greater than zero and less than or equal to 20. Provide error handling to require that the user inputs an integer (as opposed to a floating point number, see help elfun) and that the integer is in the correct range. Print a pattern with a successive number of integers (with increments of 2) in each line until the number of lines printed equals the integer that the user entered divided by 2. Each integer should be in a field that is 6 characters wide: For instance, if the user enters 8, the program should display NNNN 4 4. 8
