zeros功能是返回一个m×n×p×...的double类零矩阵的一个函数。

注意：m, n, p,...必须是非负整62616964757a686964616fe59b9ee7ad9431333366306462数，负整数将被当做0看待。

首先先列出matlab中help文件对zeros函数的解释：

ZEROS Zeros array.

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');

具体来讲，zeros(1，8)是创建一个1行，8列的零矩阵。
