What is the error in this script file?

for n=1:points

What are your error messages?

When you 'Input initial coordinate' are you entering two values at the prompt?

Last line lookin strange, Next_coord not defined and wierd braces.
coord(n+1,:) = Next_coord(coord(n,:)) , length(n), NA_RAD(n) ;

Azzi's comment points to the most efficient approach to solve your problem: What is the error message?
Matlab's error messages contain very useful information, so reading them is a good strategy, and if they do not help you directly, please post them at least in the forum. You script can contain millions of different bugs. E.g. if you have re-defined any of the used Matlab functions as local variable, almost any line could crash. An example is using "length" as a variable: Afterwards Matlab's length() function is not called anymore. This leads to strange reactions frequently.
Anyhow, the last line does not close the parenthesis properly, as Christian W has mentioned already:
coord(n+1,:) = Next_coord(coord(n,:)), length(n), NA_RAD(n) % ERROR
coord(n+1,:) = Next_coord(coord(n,:), length(n), NA_RAD(n)) % Cleaner
