Haseeb Hassan it is a big matrix of 3D. Why you want to view it? There is no necessity to see it.

The Variable Editor is not thought to display the contents of huge and/or 3D arrays. It is simply not useful to display them as a table. Therefore the behavior is expected and useful - and not a "problem". Use another tool to display the array, e.g. the image command.

Okay Sir one thing more can you make it clear, that i have a grayscale image i used the below function for it can you tell me what will do this code with this grayscale image, i know it adding the channels to gray scale image, but i am not fully aware of the situation what values it adds to grayscale(which is a single channel image).PLease explain the effect of the below function on single dimenesional image.Here is a function.
function [Image]=gray2rgb(Image)
%Gives a grayscale image an extra dimension
%in order to use color within it
[m n]=size(Image);
rgb=zeros(m,n,3);
rgb(:,:,1)=Image;
rgb(:,:,2)=rgb(:,:,1);
rgb(:,:,3)=rgb(:,:,1);
Image=rgb/255;
end

The code copies the single input channel. RGB images that look gray have their three channels equal.
The code expects a uint8 image and turns it into a double image in the appropriate range.
Another way of writing the code would be:
gray2rgb = @(Image) im2double( Image(:,:,[1 1 1]) )

I don't advise you to call your image Image since there is a built in function called image. So let's call your grayscale image grayImage. Then to create an rgb image in the range 0-1, you can simply do
rgb = cat(3, grayImage, grayImage, grayImage) / 255;
Instead of all those lines of code you were using.

Thanks Sir @ImageAnalyst and @WalterRoberson.I got you people points.Now i am doing detection in this three channel image so how useful it will be,i am compare to gray image, what advantages will this three channels image now to further crack down this three channel image as compared to single channel image(gray image).Thanks for you people responses.Cheers
