Dear All,
I want to plot ROTI. Would you please help me? The ROTI is defined as the standard deviation of ROT, given by (<ROT^2> - <ROT>^2)^1/2 for each 5-min interval.

Ran in:
x = rand(100,1) ;
y = sqrt(mean(x.^2)-mean(x)^2)
y = 0.2657

Thank you for you reply.
How to calculate standard deviation for each 5 min interval?
y=std(sqrt(mean(x.^2)-mean(x)^2));
Is that correct

You see, (sqrt(mean(x.^2)-mean(x)^2) is a single number, you cannot find stanard deviation. May be you need to find this number for every five minutes ata and then get Std of that array.

I think you are right. I have a column of time. How to write for every 5 min data and then get the std?
