I have a 400x800 matrix I want to divide it into 8x8 blocks.I know I should use mat2cell but I don't know how.here is my code dctCr,dctCb and dctY are the matrices I want to divide.
leaves = imread('leaves.bmp');
YCBCR = rgb2ycbcr(leaves);
[Y Cb Cr] = imsplit(YCBCR);
% downsample
sampledCb = Cb(1:2:end,1:2:end);
sampledCr = Cr(1:2:end,1:2:end);
% DCT ransform
Cb = double(Cb);
Cr = double(Cr);
Y = double(Y);
Cb = Cb - 128;
Cr = Cr - 128;
Y = Y - 128;
dctCr = dct2(Cr);
dctCb = dct2(Cb);
dctY = dct2(Y);

Ran in:
M = rand(400,800);
[R,C] = size(M);
C = mat2cell(M,8*ones(1,R/8),8*ones(1,C/8))
C = 50×100 cell array

Processing is usually faster if you keep the data in numeric form. Using this FEX download,
https://www.mathworks.com/matlabcentral/fileexchange/115340-block-transposition-permutation-and-reshaping-of-arrays
you can convert the original matrix into an 8x8xN stack:
A=rand(400,800);
B=blkReshape(A,[8,8], 1,1,[]);
whos A B
Name Size Bytes Class Attributes
A 400x800 2560000 double
B 8x8x5000 2560000 double
