Hi, I have a 76x102x5 cell matrix. I would like to create a single array of data from each index for n-dimensions. For example,

for k = 1:5
array  = cell{1,1,k};
end

output = [ 1 2 3 4 5 ];

so its only the numbers from the same index but in different dimensions.

What shape of data is stored in each element of the cell array? Is it certain to be consistent?

sorry, if its confusing. Ok let me try to rephrase the question. Lets say, for example, I have a 2x2x3 cell. The data stored in each element is a double, specifically a number between 0-1. I am calculating the correlation coefficient of different sections of an an image between multiple images. So i may have n = 3 pictures, meaning n = 3 dimensions in my cell array.

corrValue(:,:,1) = [1][1]

[1][1]

corrValue(:,:,2) = [0.989][0.999]

[1][0.899]

corrValue(:,:,3) = [0.899][.998]

[0.997][0.899]

I want to extract the data store in each element for the n - dimensions. So for my output. I want to get an array for the (1,1) index,

array = [1 0.989 0.899]; %(1,1) index

The reason being I want to generate a decorrelation curve for each section of the image; therefore, I need to plot the correlation coefficient with respect to the number of images i have taken.

I don't fully understand what you are trying, but lets see if this helps you

% This is just to create cell array
ar=rand(2,2,3);
ca=mat2cell(ar,ones(1,2),ones(1,2),ones(1,3));
% Now from above cell array extract double array
da=cell2mat(ca(1,1,:));
da=da(:);
