Hi all,

There is a probably a very simple solution to this but my mind has gone blank. I have a matrix which I am filtering on using logical indexing of another matrix e.g.

new_matrix=old_matrix(diff_matrix>50)

This works fine however I am trying to do the same thing, this time with a cell array e.g

new_cell_Array=old_cell_Array(diff_matrix>50)

but in this instance nothing happens - the old array and new array are the same size. Any ideas of how I use indexing to filter to the same entries in my cell array as my matrix?

I hope this makes sense

Thanks for your response - I have added the data I mentioned in my first post

When I run your code on those arrays I get a result array that is 5 elements shorter than the old_cell_array so it seems to work fine. The syntax is certainly fine since diff_matrix is a logical array.

I tried it with your variables and it worked fine.

>> size(old_cell_array)
ans =
        196.00          1.00
>> new_cell_array=old_cell_array(diff_matrix>50);
>> size(new_cell_array)
ans =
        191.00          1.00

Maybe you confused old_cell_array and old_cell_Array, or something like that?
