| std {matlab} | R Documentation |
Computes the standard deviation of the values of x.
std(x, flag = 0)
x |
numeric vector or matrix |
flag |
numeric scalar. If 0, selects unbiased algorithm.
If 1, selects biased algorithm (currently unsupported). |
Simply invokes sd.
Return value depends on argument x. If vector, returns the
standard deviation. If matrix, returns vector containing the
standard deviation of each column.
