离散控制系统设计的MATLAB 代码

function   s = vec2str(v)
%        Converts a vector (column or row) to a string that
%        prints on one line, with square brackets at both ends.
%        If v is a column vector, the elements are separated by ';'.
%Input: v - vector to be converted
%Output: s - string representation of v
