i have A=4*16384 double matrix and converted into 64*64 cell and each cell have again 4*4 double matrix ,now iam trying this below code
c = mat2cell(A,4,4*ones(64,64))
but it gives error
Error using mat2cell
Input arguments, D1 through D2, should be vectors.

Which part is your actual question? Do you want to know how to apply a function to all elements of a cell array? Do you want to know how to redivide a cell array containing matrices?

I'm going to assume you have 256x256 separated into 64x64 blocks and you want to redistribute to 4x4 blocks.
%create some data
data=reshape(1:(64*4)^2,64*4,64*4);
data=mat2cell(data,64*ones(1,4),64*ones(1,4));
A=cell2mat(data);%convert to a 256x26 matrix
B=mat2cell(A,4*ones(1,64),4*ones(1,64));%divide into 4x4 blocks

Depending on what you want as organization, either
C = mat2cell(reshape(A,4*64,4*64),4*ones(1,64),4*ones(1,64))
or
C = reshape(mat2cell(A,4,4*ones(1,64*64)),64,64) % EDIT: This is the reverse of A = [C{:}]
or ....
