y = rssq (x) ¶y = rssq (x, dim) ¶Compute the root-sum-of-squares (RSS) of the vector x.
The root-sum-of-squares is defined as
rssq (x) = SQRT (SUM_i x(i)^2)
If x is a matrix, compute the root-sum-of-squares for each column and return them in a row vector.
If the optional argument dim is given, operate along this dimension.
