We were given the code shown below as a script and told to calculate Mean and to create a method to caalculate standard deviation. He wanted us to show each iteration and what each variable was equal to. I was confused on what he meant by this and what he watned us to do.

Clear All

x = [6 6 8 4 1 9 5];

N = length(x);

j=0;

Sum2=0;

V=zeros(1,N);

for i=1:N;

j=j+1;

Sum2=Sum2+x(i);

V(j)=Sum2;

end

MN=Sum2/N

"He wanted us to show each iteration and what each variable was equal to."

It would be better if you just ask your teacher/professor for some clarification, what they meant, rather than having us to speculate about it.

Hi,

If you just want to show what value each variable will hold as value after each iteration, you can just remove the semicolon at the end of the line in the ‘for’ loop. Else you can use the disp() function to display the value of each variable.
