Cant execute my nested sub-functions

This is the question i'm stuck on:

In Problem 6.10 you were asked to create and use three different temperature- conversion functions, based on the following conversion equations: (Done in my code below) Recreate Problem 6.10 using nested subfunctions. The primary function should be called temperature_conversions and should include the subfunctions F_to_K C_to_R C_to_F Within the primary function use the subfunctions to:

(a) Generate a conversion table for values from 0°F to 200°F. Include a col- umn for temperature in Fahrenheit and Kelvin.

(b) Generate a conversion table from 0°C to 100°C. Print 25 lines in the table. (Use the linspace function to create your input vector.) Your table should include a column for temperature in Celsius and Rankine.

(c) Generate a conversion table from 0°C to 100°C. Choose an appropriate spacing. Include a column for temperature in Celsius and Fahrenheit. Recall that you will need to call your primary function from the command window or from a script M-file.

code so far is this..

function []=temperature_conversions()
function R=C_to_F(C)
%this function will convert celcius to fahrenheit
disp('C_to_F')
R=(C.*9/5)+32;
end
function R=C_to_R(C)
%this function will convert celcius to rankine
disp('C_to_R')
R=(C.*9/5)+491.67;
end
function K=F_to_K(F)
%this function will convert fahrenheit to kelvin
disp('F_to_K')
F=linspace(0,200,20);
K=(F+459.67).*5/9;
end
end

I want to try to execute this code some individually each piece works but i guess i need multiple inputs/outputs or something??

You need to put code in your primary function to call the subfunctions to create the tables. E.g.,

function []=temperature_conversions()
%
% You write a bunch of code here to create the tables by calling the subfunctions
%
function R=C_to_F(C)
