Indexing Problem
Posted:
Jun 25, 2012 1:56 PM


Hello all,
I have a matrix 'all_counts' (29 by 8 array containing data, and some NaNs). I'm trying to graph certain parts. I'm using (I believe) logicals to do this.
I've defined:
% define location vector, to be used for cuts src_loc = [ 1 1 2 2 3 1 1 3 2 1 2 1 3 3 1 3 1 1 1 1 3 1 1 3 1 3 1 2 2 ]; % (29 entries) % Define actual positions SW=src_loc==1; NW=src_loc==2; NE=src_loc==3;
Which all work properly when I ask MATLAB what they are.. (e.g. SW = row vector of 1's and 0's, and likewise for NW and NE). Here's the messed up part... I can try
all_counts(1,:)  this gives a 29by1 column of data (good!) all_counts(SW,:)  this gives all data from the Southwest source position (which is what I want)
...but when I try: all_counts(NW,:) I get: Index exceeds matrix dimensions.
What is going on here? I've tried 'clear all' and reimporting my 'all_counts' as well as the position definintion for SW, NW and NE. I really only get this error with the NW position (no matter which column I try to pick out) which is unlike my other positions calls (SW, NE)... how can I fix this?
Thank you for any help. If I've been unclear please just tell me how to clarify!!!
Michael
