**Access to cell array in cell array**Hallo.
I have a problem with a cell array.
It's a 12x2 cell array.
And in the second column in each row of this cell array is again a 13x1 cell array. In the 8th cell there is a column vector.
I tried to gain access to this column vector in the 8th cell for finding the minimum at once of all 12 cells in the second column. But I failed.
It looks like that:
samples_merged{i,2}{8,:} where i runs from 1 to 12.
I am able to solve the problem with a loop, sure, but if anyone comes up with an idea without a loop, I would be happy.
Kind regards,
Gudrun

**Breaking Up Large Cell Array into Smaller Cell Arrays**Hello,
I have a unique problem. Right now I have a large cell array and I want to break that cell array into smaller cell arrays. Here is a portion of the large cell array:

**Changing matrices in cell arrays except for one cell array in a cell**Hey guys I need your help once again! I hope someone can show me how to do this. So I have a cell MTT with "d" cell arrays in it, each cell array contains a matrix of nxn and I need to change a whole row of numbers to Inf in every matrix except for one of them which is going to be given by variable "b". MP is a matrix with a dx2 dimension. Here is my code but this will do it for all matrices, I want to find a way to not do it for "b",
for d = 1:numMachines;
MTT{d}(MP(b,2),:) = Inf;

Now I have tried doing the following but I guess I can not do...

**cell contents to non-cell array object**Hopefully a trivial question:
This part of my program below opens datafile with two columns(and

Reads in serial date, converts to string date and hopefully writes
out string date and temp value. Getting error that says:
"Cell contents assignment to a non-cell array object." Crashes during
2nd time thru for loop on stringd{i} line.
Tried {} brackets, (), parentheses...not sure if strings need to be
exact same size. Any suggestions? Thanks, Sheryl

**Cell arrays containing cell arrays**Hi Everyone,
I have data in cell arrays containing cell arrays. I would like to extract data from these cell arrays and store in a normal array. I am able to do it for a particular case using nested for loops. But I would like to generalize this problem such that I can extract any kind of cell array containing cell arrays just like cell2mat function does. Please let me know if there is any solution to this problem.
Thanks,
Anil Palaparthi.

I need to convert this into a a character array or cell array of strings.
I tried:

We can deduce that either A.data is not a cell array, or else
A.data{1,1} is not a cell array.
But as to -why- this is so... Sorry, Magic 8-Ball Is Out of Order.

**delete cells in cell array with certain cell size**Hi there,
how can I delete cells (arrays of different length) with a size==1 in a cell array?
example for an cell array C. Cells 3 and 6 have a size of 1x2 and have to be deleted:
>>C(1:6)
ans =
[13x2 single] [14x2 single] [1x2 single] [9x2 single] [11x2 single] [1x2 single]
I could manage it for empty cells using cellfun
% Empty cells in cell arrray will be deleted.
C(cellfun(@(C) isempty(C),C))=[];

**Part of cell array into another cell array**Hello
I would like to know how can I put a part of a cell array into another
cell array without use for or while loops.
For example:
"points" is a cell array of dimensions 1 x 16. The elements of
"points" consists on matrices of several sizes.
Now I want to introduce "points{1:5}" into another cell array of
dimensions 1 x 5 without using loops. How can I do this?
Thanks in advance.

I would like to know how to access a cell arrays sectors/ contents which is based on a relational operator. To make it clear
I have a cell array
