I am creating a Matlab program that calculates corresponding temperatures for Celsius, Kelvin, Fahrenheit, and Rankine scales. I want to write my code so that it can handle an arbitrary temperature increment (a user-inputted value).

Here is my current code (it currently increments by 1 degree Celsius--I want to change this):

Cstart = -50; 
Cend = 100;
for Celsius = Cstart:Cend
    Celius = Celsius
    Kelvin = Celsius + 273.15
    Fahrenheit = 1.8.*Celsius + 32
    Rankine = (Celsius+273.15)*1.8
end
plot(Celsius,Kelvin,'r')
hold on
plot(Celsius,Fahrenheit,'b')
hold on
plot(Celsius,Rankine,'g')
legend('Kelvin','Fahrenheit','Rankine','FontSize',20)
xlabel('Temperature in Celsius','FontSize',20)
ylabel('Converted Temperature','FontSize',20)
title('Equivalent Temperatures','FontSize',20)
set(gca,'FontSize',20)

Thank you in advance!

在 MATLAB Online 中打开

Cstart = -50; 
Cend = 100;
step = input('Enter the increment ');
Celsius = Cstart:step:Cend;
%for ii = 1:numel(Celcius)
    % Celius = Celsius
    Kelvin = Celsius + 273.15
    Fahrenheit = 1.8.*Celsius + 32
    Rankine = (Celsius+273.15)*1.8
%end
plot(Celsius,Kelvin,'r',Celsius,Fahrenheit,'b',Celsius,Rankine,'g')
% hold on
% plot(Celsius,Fahrenheit,'b')
% hold on
% plot(Celsius,Rankine,'g')
legend('Kelvin','Fahrenheit','Rankine','FontSize',20)
xlabel('Temperature in Celsius','FontSize',20)
ylabel('Converted Temperature','FontSize',20)
title('Equivalent Temperatures','FontSize',20)
set(gca,'FontSize',20)
