Problems with cell array

For example, I've got cell array:

c = {[10 12 13]' [4 5 6]' [7 8 9]';...
    [10 20 30]' [40 5 60]' [70 80 90]';...
    [100 200 300]' [400 500 600]' [3 800 9]' }

I need to find min in every row of c{i,j}, where i=j. So, I need to take c{1,1}, c{2,2}, c{3,3} and to find min of every row. I dont think my description is clear, so see the attached file. So the answer must be

ans = [3 5 9]'

Thanks a lot !

Answer 1

k = c(1:size(c,1)+1:end));% EDIT  (diag(c));

or

k = c(eye(size(c))>0);

out = min([k{:}],[],2);

[Nik Zakh]

Undefined function 'diag' for input arguments of type 'cell'

Sorry, I now use Octave... fixed.

[Nik Zakh]

It works ! Thanks ! Now I need to understand HOW does it work :)

[Nik Zakh]

Thanks for the previous answer ! Can you now help me to do the same thing, but for the case when i~=j ? Thanks !

[Andrei Bobrov]

variant

k = c(~eye(size(c)));
out = min([k{:}],[],2);

[Nik Zakh]

That's easy ! Thank you one more time !

min(cat(2,c{1:size(c,1)+1:end}),[],2)
