Correlate a 3d array into n times 2d rows

Hi
Was just wondering if there was a simple way to flatten a 2d array into correlation rows. Ok so here's an example:
I have n numbers of a 2d array as such:
a b c d e f
1 1.771 1.771 1.771 1.771 2.314 2.314
2 1.802 1.802 1.802 1.802 2.288 2.288
3 2.071 2.071 2.071 2.071 2.184 2.184
4 1.961 1.961 1.961 1.961 2.086 2.086
5 1.94 1.94 1.94 1.94 2.649 2.649
6 1.924 1.924 1.924 1.924 2.458 2.458
7 2.065 2.065 2.065 2.065 2.211 2.211
8 1.981 1.981 1.981 1.981 2.066 2.066
9 1.752 1.752 1.752 1.752 2.108 2.108
10 1.907 1.907 1.907 1.907 2.153 2.153
So say example here a 3d (6x10x n)
How can i correlate a1:a10, b1:b10 till f1:f10 so call them feature a1,a2,a3....f8,f9,f10 and do this for n rows. N rows of 60 features (a1,a2,a3...). Is there a simple matlab function ? Thank you for any help.
Answer for n rows is:
a1 a2 a3 a4 a5 f8 f9 f10
n1 1.771 1.802 2.071 1.961 1.94 2.066 2.108 2.153
n2
n3

example of your output?
Sure sorry say n number of rows:
a1 a2 a3 a4 a5 f8 f9 f10
n1 1.771 1.802 2.071 1.961 1.94 2.066 2.108 2.153
n2
n3

Don't even think of creating numbered variables use cell instead
matrix=yourmatrix';
n=size(matrix,1);
result=cell(1,n);
for i = 1:n
result{i}=matrix(i,:);
end
celldisp(result)

Ok so everything is in cell form. Can you help with the problem?

what's your problem now? Did you get any error or what? if so paste everything in red else what's your desired result give a sample and the expected result..

"Can you help with the problem?"
What exactly is the problem? Your numeric array can be indexed already, very efficiently using MATLAB's standard indexing.

In an assignment A(:) = B, the number of elements in A and B must be the same.
Error in addHeader (line 19)
result(i)=matrix(i,:);
my matrix is 165x165x59 cell

{ } instead of ( )
n=size(matrix,3);
^--change it to 3 from 1
result{i}=matrix{:,:,i}
If it's not what you are looking for attach your matrix as .mat file
