Re: Not Average

[ianwaugh@xxxxxxxxx (Ian Waugh)]

Thanks to everyone who suggested I use a second variable to store the 
average value in like this:

 diff=c-c[1];
 diff1=average(diff,3);
 plot1(diff1,"diff");
 
Someone said the problem happens because "diff" has already been used. I 
was trying to be thrifty (:-). However, I thought you were allowed to 
change the value of a variable by referencing itself such as:
 
count=count+1;

So I assumed my version would work. Is there some obtuse aspect of EL at 
work here?
