B = zeros(256,256);
B(1:size(A,1),1:size(A,2)) = A;  %upper left
B(end-size(A,1)+1:end, 1:size(A,2)) = A; %lower left

With obvious generalizations to upper right and lower right

c = floor((size(B)-size(A))/2);
B(c(1)+1:c(1)+size(A,1), c(2)+1:c(2)+size(A,2)) = A;  %center

The centering algorithm biases towards the upper left if the sizes are not both even or not both odd.

Dear sudipta,

I have downloaded your data file, and went like

a=load('1372387722318.txt');
y=reshape (a,256,256);
whos 
Name          Size              Bytes  Class     Attributes
a         65536x1              524288  double              
y           256x256            524288  double

and everything is just fine to me. So, the only possible error is that: you have another file with a name (fname.txt) in your directory which is not the same file you uploaded (1372387722318.txt). Check this out and I'm pretty sure you'll have it working.

Regards
