Index of element to remove exceeds matrix dimensions??!

Hello Everybody; i am having a problem with that code, regarding that i want to discards the columns with value less than 3...but it always gives me Index of element to remove exceeds matrix dimensions

can you please help me through that?!

    [orderedCount, SortOrder]=sort(Count,'descend');
         Items=Items(SortOrder);
        %%%the propabilty of presence of each
     for i=1:length(orderedCount)
    if(orderedCount(i)<3)
    items(i)=[];
    end
    end

Looping will not work because the length and indexing of "Items" changes each time you remove an element. You must remove all of the elements simultaneously,

Items(orderedCount<3)=[];

Thanks A lot for answering me; appreciated i see, but also this string you send didn't work!

it gives me the same message...

If you're skeptical that it should work, the following example should convince you

>> orderedCounts=1:5, Items=rand(1,5)

orderedCounts =

       1     2     3     4     5

Items =

      0.7968    0.8358    0.6185    0.0703    0.1784

>> Items(orderedCounts<3)=[]

Items =

      0.6185    0.0703    0.1784

    >>orderedCount =

      Columns 1 through 12

         9     8     6     6     6     4     4     4     4     3     3     3

      Columns 13 through 24

         3     3     2     2     2     2     2     2     1     1     1     1

      Columns 25 through 27

         1     1     1
    >>Items 

    Items =

      Columns 1 through 12

         4    12    13    18    30     6    10    15    22     8    24    26

      Columns 13 through 24

        27    29     1     5     7     9    16    28     2    11    17    19

      Columns 25 through 27

        20    21    23

code:

 for i=1:length(orderedCount);
 if orderedCount(i)<3 ; 
 Items(orderedCount<3)=[];
 end
 end

where is the problem here to give me this message ??? Index of element to remove exceeds matrix dimensions.

Error in ==> FPNEW at 44 Items(orderedCount<3)=[];

As I mentioned, and as my example showed you, this should be done without a loop. The single line

   Items(orderedCount<3)=[];

will do the whole job.

It is brilliant , i thought i have to enter it in the loop,

it works and i am very thankful for your precious help :)
