共振隧穿二极管的matlab建模...各种串联、并联模型

x=0:0.001:1

y1off=0.0143*x.^3.*(atan(38.3.*(x-0.1))-atan(38.3.*(x-0.4)))+ 0.00263* x.^5-0.0000159*x.^3


y1open=0.0143*x.^3.*(atan(38.3.*(x-0.1))-atan(38.3.*(x-0.4)))+ 0.00263* x.^5-0.0000159*x.^3

+f(x)


y2=0.032*(1-x).^3.*(atan(38.3.*((1-x)-0.1))-atan(38.3.*((1-x)-0.4)))+
0.0059*(1-x).^5-0.0000358*(1-x).^3


plot(x,y1off,x,y1open,x,y2)


about f(x):

function ret=f(x)
c0=0.02;
c1=0.5;
c3=0.0025;

y=[];
for t1=x
    if t1<=0.5
        y=[y,1];
    else y=[y,0];
    end
end

ret=c0*(c1*x-0.5*x.^2).*y+c3*abs(y-1);

用画图法求得：
