在做一个simulink仿真，请告诉我下面语句是什么意思，改怎么操作？

Next let's try a raised cosine (RC) pulse （升余弦）with 30% excess bandwidth.
, |7 {: ~+ I- HCopy the RC Pulse program called "rcpuls" on page 23 of the Anderson text into a file called "rcpuls.m".  Or cut and paste from here...
function y = rcpuls(a,t)tau = 1; % Set the symbol timet = t + 10^(-7); % This avoids dividing by zerotpi = pi/tau; atpi = tpi*a;at = 4*a^2/tau^2;y = sin(tpi*t).*cos(atpi*t)./(tpi*t.*(1-at*t.^2));
Now create an RC pulse by entering the following at the Matlab prompt.
rcpulse = rcpuls(.3,[-6:0.01:6]);

可以试试楼上的方法

创建个叫“rcpuls.m"的文件，其内容是function y = rcpuls(a,t)tau = 1; % Set the symbol timet = t + 10^(-7); % This avoids dividing by zerotpi = pi/tau; atpi = tpi*a;at = 4*a^2/tau^2;y = sin(tpi*t).*cos(atpi*t)./(tpi*t.*(1-at*t.^2));
" e5 S/ M; _5 q- h6 d8 q% |然后在matlab的提示符下输入rcpulse = rcpuls(.3,[-6:0.01:6]);
