myplot.m

对波形进行统计特征分析的程序

function myplot()


h=findobj(gcf,'tag','strb');
h1=findobj(gcf,'tag','mu');
filein=get(h,'string');
mu=eval(get(h1,'string'));
%z=load(filein);
load(filein);
x=z(:,1);
y=z(:,2).*mu;


%positive_index=find(x<=30000);
%negative_index=find(x>=30000);
%y(positive_index)=-abs(y(positive_index));
%y(negative_index)=abs(y(negative_index));
figure(1)
plot(x,y,'.')
hold on
x1=linspace(0,60000);
y1=sin((x1./60000).*(2*pi));
a=max(abs(y));
y1=y1*a;
hold on
plot(x1,y1)
