Question

How can I read a file and use the content to find the answer?

3. Write a MatLab program that reads in the set of values in the file "Values.txt" which is available from the d2l website. The values are stored as ASCII text separated by carriage returns, so you can open the file and look at the valucs yourself by double clicking on the file name in MatLab's Current Directory window. Your program should next calculate and print out: 1. The mcan of the data set 2. The standard deviation of the data set You must write all of this code yoursef, without using any of MatLab's built-in statistical func tions or the sum () function. Hand in a printout showing the results you obtain.

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

clc
clear all
close all
m=0;
st=0;
A=load('Values.txt');
%A=randi(10,10,1);
for i=1:length(A)
m=m+A(i);
end
m=m/length(A);
for i=1:length(A)
st=st+(A(i)-m)^2;
end
st=sqrt(st/(length(A)-1));
disp('Mean is');
disp(m)
disp('Standard ddeviation is ');
disp(st);
