Matlab - Exercise 12

For each of the following, decide whether you would use a for loop, a while loop, a nested loop (and if so what kind, e.g., a for loop inside of another for loop, a while loop inside of a for loop, etc.), or no loop at all.

• sum the integers 1 through 50
• add 3 to all numbers in a vector
• prompt the user for a string, and keep doing this until the string that the user enters is a keyword in MATLAB
• find the minimum in every column of a matrix
• prompt the user for 5 numbers and find their sum
• prompt the user for 10 numbers, find the average, and also find how many of the numbers were greater than the average
• generate a random integer n in the range from 10 to 20. Prompt the user for n positive numbers, error-checking to make sure you get n positive numbers (and just echo print each one)
• prompt the user for positive numbers until the user enters a negative number. Calculate and print the average of the positive numbers, or an error message if none are entered
