??? Assignment has more non-singleton rhs dimensions than non-singleton subscripts

% my array declaration
imgarr=zeros([5,3,nFrames]);

% Create topleft quantized image
[img1,map] = rgb2ind(tl,64);

% color planes for topleft image
tl_rPlane = reshape(map(img1+1,1),size(img1));  % Red color plane for image
tl_gPlane = reshape(map(img1+1,2),size(img1));  % green color plane
tl_bPlane = reshape(map(img1+1,3),size(img1));  % blue color plane
imgarr(1,1,k)=imhist(tl_rPlane); % storing histograms for the 3 color planes to the kth dimension of the array..
imgarr(1,2,k)=imhist(tl_gPlane);
imgarr(1,3,k)=imhist(tl_bPlane);

my error:

??? Assignment has more non-singleton rhs dimensions than
non-singleton subscripts

Error in ==> modified at 42
imgarr(1,1,k)=imhist(tl_rPlane);

i need to store the histogram values of the three color planes to the array please do help me...im totally a newcomer to matlab...

imhist replies a vector, but imgarr(1,1,k) is a scalar, if k is scalar. Perhaps you want imgarr to be a cell array:

imgarr = cell(5,3,nFrames);
...
imgarr{1,1,k} = imhist(tl_rPlane);

You can store only vectors of the same length in an numerical array, but in a cell array all elements can have different type and size. As a drawback, it is much harder to perform calculations with cell arrays, of course.

Thank u boss....i was a bit confused with cell array and numeric array concepts.... :)
