Hi guys,
I want to find the intersection of y3 and y4,
x=(0:0.5:80).';y1=(0.02049/0.4)*x;y2=(0.53*60./(1+(1.331./(sqrt(0.0631*x./(83.18-x))).^3)));y3=(0.53*60./(1+(1.331./(sqrt(0.0631*x./(83.18-x))).^3)))-(0.02049/0.4)*x;y4=(0.02049/0.4)*x-(0.53*60./(1+(1.331./(sqrt(0.0631*x./(83.18-x))).^3)));figureplot(x,y1,'r')hold on plot(x,y2,'c')plot(x,y3,'g')plot(x,y4,'b')legend('Line1','Line2','Line3','Line4')axis([0 80 -1 3.5])
i tried to use
C = intersect(y3,y4)
I get C = 0, but I want the intersection near x = 70;
