Sorting a Cell Array



25 Jan 2007 (Updated )

This function will sort a cell array even if it is mixed.

File Information

This function sorts a cell array, even if it contains character strings and numeric values (i.e. mixed). The only restriction is that it assumes that each column contains either numeric values or character strings, not both. It sorts the rows in ascending order. Note that it allows more than one column to be sorted according to the priority input by the user.

Matlab function: sortrows() does this.

Good job.
I use uigetfile to load a number of images (say, image001 to image078) in my code. When I run my code, I click on image001, push shift key, and then click on image0078. As a result in the uigetfile cell array I get this order: image078, Image001, image002, ..., image076, image077, which caused many terrible so far. Using sortcell, the problem is solved.

Simple and efficient. Cheers bro

Just a note to anyone who wanted to use this for the same purpose as me.

If you have a cell array of strings, but want to sort by a column that contains numeric values as class string (i.e.


sort is notorious for treating strings a character at a time. So, if I used this function on the above vector, 20 would be sorted after 100 on account of the character 1 coming before 2.

I understand that this function would work wonderfully if that entire column was a number instead of a string containing a number, but depending on the application it may not be possible to force the class to double. In my case, I don't know if that column is going to contain strings or numbers until I need to sort it, so I ended up going my own route.

Very useful program though, thanks for sharing on FEX!

Correct that! The last line should read:
ix = ixin(ix);

Solved for now. Maybe I will update this function at a future time point to implement the above. For now:

[data, ixa] = sortcell(data, 11);
[data, ixb] = sortcell(data, 12);
[data, ixc] = sortcell(data, 1);
[data, ixd] = sortcell(data, 5);

Desired would be:
[data, ix] = sortcell(data, [11 12 1 5]);

Would there be an easy way of getting the overall permutation vector for a multidimensional sort? For one dimension it is easy (just return ix defined at line 108) but when using multiple dimension only the last value of ix is returned. I was thinking to implement something like ix(ix) but that of course does not work. Suggestions welcome!

Great, it worked. Thanks, it saved me a lot of time!

i have
for m=1:100;
for k1=1:1:22
here k1 is filename of image so total Nfiles are 100
for i=1:1:Nfiles
for k1=1:1:22

A(i)is the value which is corresponding to the file name i want to sort filename with respect to A(i)
what i can do
above code show it in serial that means from 1 to 100 without sorting

Folks I tried following to re arrange the data in desending way.
for i = 1: length(SortedData)
NewCellArray(k,:) = SortedData(length(SortedData)+1-i,:);

Great. Thanks !

Thanks a lot, you save my life! :)

Works well for sorting in one dimension. Produces errors in you try to order with two or more dimensions. TO fix this, edit line 77 so that it reads:
X = sortcell(X, col,MODE);

Also, if two dimensions are used, the order is not preserved from the first sort to the second, which is very confusing.

does exactly what I need; thank you

great useful function. Thanks for writing it, it saved me some time

I uploaded a previous bugged version, not the final one, sorry folks.

This script was updated to add the functionality for sorting according to the desired user specified direction (ascending or descending).
