Matlab之zeros

zeros(n)：返回n by n值为零的矩阵

zeros(m,n) or zeros([m n]):返回m by n值为零的矩阵

zeros(m,n,\'single\'):返回single（单精度）的m by n零矩阵，single可以为double等

matlab中解释如下：

% ZEROS(N) is an N-by-N matrix of zeros.

%

% ZEROS(M,N) or ZEROS([M,N]) is an M-by-N matrix of zeros.

%

% ZEROS(M,N,P,...) or ZEROS([M N P ...]) is an M-by-N-by-P-by-... array of

% zeros.

%

% ZEROS(SIZE(A)) is the same size as A and all zeros.

%

% ZEROS with no arguments is the scalar 0.

%

% ZEROS(M,N,...,CLASSNAME) or ZEROS([M,N,...],CLASSNAME) is an

% M-by-N-by-... array of zeros of class CLASSNAME.

%

% Note: The size inputs M, N, and P... should be nonnegative integers.

% Negative integers are treated as 0.

%

% Example:

% x = zeros(2,3,\'int8\');
