zigzag扫描matlab,Zigzag逆扫描

Zigzag逆扫描代码 MATLAB版

即将一个1 * k 长度的向量，逆扫描为 M * N 的矩阵(如果 k < M * N，则在 M * N 的矩阵中用 0 补齐；若 k > M * N，则向量会被截断)。

代码如下，仅供参考。

function mtr = izigzagScan(vec, m, n)

% izigzagScan(vec, m, n) Inverse zigzag scan.

% mtr = izigzagScan(vec, m, n) inverse zigzag scan of vec, and the target

% matrix is m-by-n. The input parameter vec is an 1-by-k vector. If the

% length of vector is smaller than the size of mtr (i.e. k < m*n), then, the

% pargram will use 0 to fill the matrix. If k > m*n, the vector will be truncated.

% CHECK INPUT ARGUMENTS

if nargin < 3

error('Not enough input arguments!');

elseif nargin > 3

error('Too many input arguments!');

end
