PLEASE HELP WITH THE CODE. IM GETTING A WRONG VALUE FOR STANDARD DEVIATION. Just use any ascii values and i will use the required file. I just need help with the standard deviation calculation

3. Write a MatLab program that reads in the set of values in the file "Values.txt" which is available from the d21 website. The values are stored as ASCII text separated by carriage returns, so you can open the file and look at the values yourself by double clicking on the file name in MatLab's Current Directory window. Your program should next calculate and print out: 1. The mean of the data set 2. The standard deviation of the data set You must write all of this code yourself, without using any of MatLab's built-in statistical func- tions or the sumO function. Hand in a printout showing the results you obtain I need the MATLAB code please
