Re: std

[Juan Pablo Carbajal]

Hi,

You need to get use to read the help of the functions. The third input
argument of std indicates along which dimension the function will
compute, that is 1 for "along columns", 2 for "along rows", 3 for
"along pages" (in a 3D matrix), etc...

We do not understand what you want to do with. If you explain what you
mean by "5 elements" we can give better answers.

std (vv(end-4:end))
ans =  186.01

If you want std on a moving window of size 5 you can do

movstd(data, 5)
ans =

    79.955
