NaN problem in my plot
显示 更早的评论
t=linspace(-1.5,1.5);
y=(1/(2*pi))*((exp(-t.^2)-exp(-(pi+2)*t.^2))/(t.^2)+(pi-1)*exp(-t.^2));
plot(t,erfc,'b--o')
this function for t=0 should be erfc=1, but at the plot gets the price y=3...., what's wrong

You are calling the mathematical function erfc with no arguments, right after you compute y but ignore the value of y. Perhaps you intend to plot erfc(y)
