Matlab源代码

参考以下代码1：

function H = hadamard(n,classname)

%HADAMARD Hadamard matrix.

% HADAMARD(N) is a Hadamard matrix of order N, that is,

% a matrix H with elements 1 or -1 such that H'*H = N*EYE(N).

% An N-by-N Hadamard matrix with N > 2 exists only if REM(N,4)=0.

% This function handles only the cases where N, N/12 or N/20

% is a power of 2.

%

% HADAMARD(N,CLASSNAME) produces a matrix of class CLASSNAME.

% CLASSNAME must be either 'single' or 'double' (the default).
