Matlab 使用栈判断括号是否匹配

function y = balance1(x)if nargin == 0    x = '))()())';endstack = [];try    for i = 1 : length(x)        if strcmp(x(i),'(')            stack(end+1)=1;        elseif strcmp(x(i),')')            stack(end) = [];        end    endcatch    y = false;    returnendy = isempty(stack);end
