Matlab chokes on 'end' operator

I am trying to run a script and cannot go beyond the line that plots
% Plot the relative Position Error for an entire week after the epoch time
% of the latest ephemeris
TIME = VAL(10,end-1):60/86400:VAL(10,end)-60/86400;
P1=figure;plot(TIME(end-10079:end),POSERR);
the error I'm getting is
- _ *Subscript indices must either be real positive integers or logicals* _ *
all variables have been defined

What are the dimensions of the variables involved? Have you used the debugger to pause execution at that line to verify the variable dimensions?

Looks to me like it should be okay. Try putting parentheses around "end-1" and "end-10079" and see if that fixes it. If it doesn't then set
lastTimeIndex = length(TIME);
lastValIndex = size(VAL, 2);
and then use lastTimeIndex and lastValIndex instead of end and see if that works.
Do you want parentheses around "VAL(10,end)-60/86400" or not. That's another thing to check.

Glad it worked. Please go ahead and mark the answer as "Accepted" then.
