my plot line is not showing line, how do i fix this?

disp ('fahrenheit(f)    celcius(cel)    kelvin(kelv)    Reaction rate(react)')
for f=50:1:104
    cel=(f-32)/1.8;
    kelv=(f+459.67)/1.8;
    A=10^11;
    e=2.71828;
    Ea=7.5*10^4;
    Rt=8.314*kelv;
    react=(A*e^(-Ea/Rt));
    q=[f;cel;kelv;react];
    fprintf('%8i   %15.5f   %15.5f  %22.5f\n',q); 
end
close all
x=linspace(-1000*3.14,1000*3.14);
y1=react;
y2=cel;
plot(x,y1,x,y2)

The code needs a bit of tweaking, however the first problem is that ‘cel’ and ‘react’ need to be subscripted, and ‘q’ modified accordingly:

disp ('fahrenheit(f)    celcius(cel)    kelvin(kelv)    Reaction rate(react)')
for f=50:1:104
    cel(f)=(f-32)/1.8;
    kelv=(f+459.67)/1.8;
    A=1E+11;
    e=2.71828;
    Ea=7.5*10^4;
    Rt=8.314*kelv;
    react(f)=(A*exp(-Ea/Rt));
    q(:,f)=[f;cel(f);kelv;react(f)];
%     fprintf('%8i   %15.5f   %15.5f  %22.5f\n',q); 
end
close all
x=linspace(-1000*3.14,1000*3.14,f);
y1=react;
y2=cel;
plot(x,y1,x,y2)

I also changed the e^ to exp.

it works now, thank you so much

As always, my pleasure!
