st_deviation - standard deviation (row or column-wise) of vector/matrix
11
x : real vector or matrix
16
st_deviation computes the "sample" standard deviation, that is, it is
17
normalized by N-1, where N is the sequence length.
19
For a vector or a matrix x, y=st_deviation(x) returns in the scalar y
20
the standard deviation of all the entries of x.
22
y=st_deviation(x,'r') (or, equivalently, y=st_deviation(x,1)) is the
23
rowwise standard deviation. It returns in each entry of the column
24
vector y the standard deviation of each row of x.
26
y=st_deviation(x,'c') (or, equivalently, y=st_deviation(x,2)) is the
27
columnwise st_deviation. It returns in each entry of the row vector y
28
the standard deviation of each column of x.
