How to increment a for loop by an arbitrary value?

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!

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)

Moreover, you cannot plot this way. I modified it so that Celcius doesn't stay a scalar. Also, you can skip the looping.

Thank you so much! Very very helpful! :)

You're welcome. Fontsize 20 is a little bit large for me, but your choice, so I didnot changed that.

[Kelsey]

I agree, but once I paste it into a document and scale it, usually it needs to be pretty big in order for the labels to not be super tiny.

[Amit]

Also, can you accept the answer when they work for you. You have never accepted a single answer from all the questions you've asked.

[Kelsey]

How can I get the Celsius value to show up in the Command Window (but not on the graph)?

[Amit]

Type

Celsius

After you have run the code. This will show the Celsius vector on command line.

[Kelsey]

Okay great! Is there any way to have it show up automatically?

[Amit]

Remove the ';' from Celsius as

Celsius = Cstart:step:Cend
