Thread Subject: Error using ==> cellfun

Hi all.

I got the following error when executing my program

%Error using ==> cellfun%
%Input #2 expected to be a cell array, was double instead.%

How can I correct this error?

my program is attached as follows:

Thanks in advance.

network = cat(3, [ 11 12 0;
                             0 0 11;
                             0 0 12;
                             0 0 0;
                             0 0 0 ], [21 22 0;
                                              0 0 21;
                                              0 0 22;
                                              0 0 0;
                                              0 0 0]);
ind = ~cellfun(@isempty,network);
[rx,cx,dx]=find(ind(:,sum(ind)>1));

"empty" is not the same as "being zero"

find(network ~= 0)

Suppose i change the network to something as follows:

test = cat(3, { [11] [12] [];
                              [] [] [11];
                              [] [] [12];
                              [] [] [];
                              [] [] [] }, { [21] [22] [];
                                                         [] [] [21];
                                                         [] [] [22];
                                                         [] [] [];
                                                         [] [] [] } );
ind = ~cellfun(@isempty,network);
[rx,cx,dx]=find(ind(:,sum(ind)>1));

The statement that i had wrote earlier can be used in this context.

What i need to obtain is something as follows:
% row/Col/Page
    2/3/1
    3/3/1
    2/3/2
    3/3/2

but, the results does not tally if you run the program. How can I solve the problem?

Thanks for any suggestions.

Hi all.

I am still stuck with this problem that i have mentioned earlier.

Can someone help me in this?

Thanks in advance.

a hint:

simply use the solution, which was shown to you 2 days ago at

http://groups.google.com/group/comp.soft-sys.matlab/msg/e5f92e263af17f3c

in a loop...

us

Ya.

I tried the solution.

ix=sum(~cellfun(@isempty,test))<=1;
     test(:,ix)={[]};
     [rx,cx,dx]=find(~cellfun(@isempty,test));

but it does not display the correct result. The value of dx is a logical value, not the page number of the multi-dimensional array. Only value of the rx and cx is correct.

how can I amend the statement so that it will store the correct address of the multi-dimensional array?

Thanks.

Seems like you should use a loop, but if you insist on a "vectorized" approach, here is one.



test = cat(3, { [11] [12] [];
                              [] [] [11];
                              [] [] [12];
                              [] [] [];
                              [] [] [] }, { [21] [22] [];
                                                         [] [] [21];
                                                         [] [] [22];
                                                         [] [] [];
                                                         [] [] [] } )

idx2 = repmat(sum(~cellfun(@isempty,test))>1,[size(test,1),1,1]);
test(~idx2) = {[]};
idx4 = ~cellfun(@isempty,test);
[rx,cx,px] = ind2sub(size(idx4),find(idx4));

rx_cx_px = [rx,cx,px]

rx_cx_px =

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




NZL0jRq_P[D`8YLZZj[jLdYPMjTSLXVqPZP_WWNTjj%ZXLL+SxL`jS_ZajM

Now that I am a little more awake, I see we can get rid of the second cellfun call:

idx1 = ~cellfun(@isempty,test);
idx2 = repmat(sum(idx1)>1,[size(test,1),1,1]);
idx3 = idx2 & idx1;
[rx,cx,px] = ind2sub(size(idx3),find(idx3));

rx_cx_px = [rx,cx,px] % The results.

rx_cx_px =

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

It is a simple, silly, alphabetic substitution-transposition enciphered message (always the same), open to anyone, with a Matlab 'twist.'
