在运行的时候会显示错误怎么办？

%%%%%%%%%%%%%%%%%%%%%%%%%%%加载声音数据%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

load voice.mat

y=m1(2,: );

x=y+0.08*randn(1,length(y));

%%%%%%%%%%%%%%%原声音信号和加噪声后的信号%%%%%%%%%%%%%%%

figure(1);

subplot(211);plot(m1(1,: ),m1(2,: ));xlabel('时间');ylabel('幅度');title('原声音信号');

subplot(212);plot(m1(1,: ),x);xlabel('时间');ylabel('幅度');title('加噪声后的信号');

这个地方y=m1(2,: )在运行的时候会显示错误，我没有懂这句代码，，请教大神，非常感谢！
