Not enough input arguments when they are already defined

Hi,

I created a new function and function file "theiss", I need to call the function in another script "Part1" with defined input variables but keep getting "Not enough input arguements" on the "Part 1" file. I do not want to set default inputs on the original function. First code below is the function file with the name "theiss.m", then the next, seperate script "Part 1" is below it

thank you

function [ux] = theiss(r,S,T,t)
ux = theiss((r^2 *S)/(4 * T * t));
end



%Part1 which is a seperate script file
T = 4706;
S= 0.00072;
t = 14610 ;
r = 7500 ; 
ux = theiss(7500,0.00072,4706,14610);

% I have also tried
T = 4706;
S= 0.00072;
t = 14610 ;
r = 7500 ; 
[ux] = theiss(r,S,T,t)

Your function theiss calls itself with one input; that's the reason for the error.

function [ux] = theiss(r,S,T,t)
% theiss calls theiss here, with one input, which has value (r^2 *S)/(4 * T * t):
ux = theiss((r^2 *S)/(4 * T * t));
% so in that call to theiss, arguments S, T, and t are not given and you get
% the error when it tries to do (r^2 *S)/(4 * T * t) for the next call to
% theiss ...
end

Perhaps the function should be defined as:

function [ux] = theiss(r,S,T,t)
% just calculate ux and return it
ux = (r^2 *S)/(4 * T * t);
end

AH! I see my error, thank you for your help!
