Whenever I run this code I get this error. The code is attached. The error is:
??? Input argument "sym" is undefined.
Error in ==> ARM_deco at 10 if(length(sym)==length(p) && sum(p)==1)

how did you call Arithmetic_dec(sym,p,tagword)? Did you just click on the green triangle, which doesn't supply any input arguments (I think this was most likely what you did), or did you give a bad value for sym, like
Arithmetic_dec([],1,'bombs')

Image Analyst-I just modified the first line of the code to
function[]=Arithmetic_dec(sym,p,tagword,varargin)
but it still shows the same error. Kindly tell me what exactly I must do.Thanks

Why don't you make a tests script to assign input variables and call this function? If you just want to click the green triangle, then don't have any arguments at all and just assign them inside the function. Or get rid of the function line and turn it into a simple script.
