From: Eamonn B on 4 Apr 2010 11:15 I have a matrix with points and I have a for loop that will go through each of these points and if a condition is met it will delete one of the points from the list. But I want to reset the loop once it has deleted a few points as I get an error once my incrementing variable get too high for my formula. I have it so that once it reaches a point I want to reset n (my incrementing variable) t=mArrayLength-length(a); if t==-1 n=0 prevPoints(:)=[]; end That is what I currently have but it doesnt seem to go through the the for loop again.
From: nickchng on 4 Apr 2010 11:39 If I understand you, perhaps a while loop is more appropriate if your loop is of an unknown length. The pseudocode would be: counter = 1; while list_not_too_long __check matrix __if deletion necessary ____delete point ____check #deletions ____if #deletions too large ______counter = 1; ____else ______counter = counter +1; ____end __end end

Don't delete the points inside the loop. Create a logical array the same size as the array from which you're deleting and set the appropriate element of that array if it meets your deletion criteria, then delete all the marked elements after the loop is complete. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ |
