%NORM   Matrix or vector norm.
%     NORM(X,2) returns the 2-norm of X.
%
%     NORM(X) is the same as NORM(X,2).
%
%     NORM(X,1) returns the 1-norm of X.
%
%     NORM(X,Inf) returns the infinity norm of X.
%
%     NORM(X,'fro') returns the Frobenius norm of X.
%
%   In addition, for vectors...
%
%     NORM(V,P) returns the p-norm of V defined as SUM(ABS(V).^P)^(1/P).
%
%     NORM(V,Inf) returns the largest element of ABS(V).
%
%     NORM(V,-Inf) returns the smallest element of ABS(V).
%
%   By convention, NaN is returned if X or V contains NaNs.
%
%   See also COND, RCOND, CONDEST, NORMEST, HYPOT, VECNORM, NORMALIZE.
