converting decimal matrix to binary matrix

I wish to convert a matrix of decimals to a matrix of binary numbers.
For example, if M = [ 1 25 34 9 ]
I then want, M = [ 00000001 00011001 00100010 00001001]
I got the output for the following matrix M=[6 5;1 3] from the below code.,but it doesn't work on the above matrix
% M=[6 5;1 3];
% b=dec2bin(M');
% b=b';
% b=str2num(b(:));
% b=reshape(b,8,2)'
*Any help/pointers would be appreciated.*

M = [ 1 25 34 9 ]
out=cellstr(dec2bin(M,8))'

Do you want the output in strings, as cells, or as numbers?
M = [ 1 25 34 9 ]
Mstr = dec2bin(M,8) % char array
Mcell = cellstr(dec2bin(M,8)).' % cell array
Mnum = dec2bin(M,8)-'0' % numerical array

thanks a lot :) it worked !!
In the same way i applied your code for the image i.e.,reading the values of image and converting it to binary matrix.
I=imread('lena.jpg');
J=dec2bin(I(:),8)-'0'; % numerical array
but when i tried to access J it shows " Cannot display variables with more than 524288 elements."
Is there any solution
thanks in advanceee
Show parts of it
p = 1:100
disp(J(p,:))
But are you sure this is the most efficient way to look at your data?

how can i make binary matrix from decimal matrix, suppose i have A=[2 3 4, 5 6 7, 1 2 1, 7 8 9] matrix and i want this like B=[1 1 1, 1 1 1, 0 0 0, 1 1 1]
