Matlab

3. Practice Problems 1) Create a vector of 20 random number between 0 and 50 (use the rand command) Remember to use the help rand' to get more info about the rand command if need be. a. Find the minimum and maximum values in the vector using a loop. Double check your answer by using the min and max functions. b. Find the sum of the values in the vector using a for loop. Double check your answer by using the sum function. 2) Create a vector of 10 random number using x=floor(rand(1,10)*5). Create a loop that will print the grade for each value according to the following table (Use fprintf command) Grade Score Score = 4 Score = 3 Score = 2 Score-1 Score = 0 Add the matrices A and B using a for-loop. - 5 4 -3 A = 1 0 1 B = 9 4 2 -10 -3 5 Afterwards, check your answer using the built-in + matlab operator. Perform the element-by-element multiplication D. E using a for-loop: - 1 -9 2 D = 7 4 3 2 3 -10 4 5 6 Afterwards, check your answer using the built-in. matlab operator
