This MATLAB function returns the standard deviation of the elements of A along the first array dimension whose size does not equal 1.
MATLAB Online에서 열기 So did you try sum, like theSum = sum(grades); and do you know about the length() or numel() function? Using those, getting the mean is trivial. Hint for standard deviation: squareGrades = grades .^ 2; ...
I know function "std" can get an array's standard deviation; but now I want to calculate standard deviation with certain weights for each number of array; for example, X=[1,2,3,4,5]; and weights=[0.1,0.3,0.1,0.3,0.1]; so is there the built-in function in Matlab?

The ssm function returns an ssm object specifying the functional form and storing the parameter values of a standard linear Gaussian state-space model for a latent state process xt possibly imperfectly observed through the variable yt.
This MATLAB function estimate standard deviation of portfolio returns for PortfolioCVaR or PortfolioMAD objects.
standard deviation in matlabSorry for asking: Is the "mean_value" the mean of the values?!instead. In general, you're probably better off not hardcoding numbers like "400" (same goes for the loop indices). This is a lot more flexible since it works for any ROI size.
