MATLAB: Help debugging the script

differential equationserrorfunctionoutputvectors

This script is meant to solve a set of differential equations and return an output consisting of the quantities [T,X,Y,Z,U,V,W] in the form of a vector. When i run the code nothing appears, only the name of my m-file in the command window. Could someone help me find where in my code I've made a mistake?

You wrote a while condition that will never be true. Have a look at this line:

while n <= n-2

For what values of n can this be true? Can you think of any real value of n where it is less than or equal to itself minus two? Try some real number examples, if you are not sure what is going on, e.g.:

n = 5
5 <= 5-2
5 <= 3

Is this ever going to be true?

i = 1;
while i <= n-2
      i = i +1;
      % write all your code
      % here. This will produce 
      % the same results as the 
      % for loop.
end

MATLAB: Not enough input arguments

Why don't you step through it with the debugger? We can't run your code because you didn't supply us with values for the input arguments n,L,Tend,nplots,D,& e. What did you pass in for those?

Say, you didn't just try to run the program by typing F5 or clicking the green run triangle, without passing in values, did you? Of course, you can't do that. What could it possibly use for n,L,Tend,nplots,D, & e? It can't just guess. You have to tell it.
