blockproc() can do that. I'm attaching two examples that you will easily be able to use directly or modify.

MATLAB: Hi, i have 170x170x36, (i.e,rows=170,col=170,images=36),i need to divide 36 image into 4 equal halves and find max value in each halves, so that i will get 2x2x36 as a final result.

divided_Array = mat2cell(YourArray, [85 85], [85 85], 36);

Now divided_Array{1,1}, {1,2}, {2,1}, {2,2} all exist and you can take their max()

MATLAB: How to segment (divide) an image into 4 equal halves

I1=I(1:size(I,1)/2,1:size(I,2)/2,:);
I2=I(size(I,1)/2+1:size(I,1),1:size(I,2)/2,:);
I3=I(1:size(I,1)/2,size(I,2)/2+1:size(I,2),:);
I4=I(size(I,1)/2+1:size(I,1),size(I,2)/2+1:size(I,2),:);

try this out, it will do
