hello,
here is the updated patch. Having consulted Matlab this time (but not
the sources :), I also added special handlers for the vector
pseudonorms with p = -Inf (minimum), p = 0 (Hamming distance - missing
in Matlab). The general case of p < 1 is now also allowed for vector
norms (not matrix), because the expression sum(abs(x).^p).^(1/p) makes
sense, though it does not define a norm.
