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),:);

"Ok No problem"
So, can you put some effort into your work? People are trying to help you. Reading your most recent reply to IA's answer genuinely made me laugh.

I was do preprocessing to my image by adaptive medain filter and i was make frame to my image 4 frame for each image. And i was extrct feature using haralick And now i need some one to help me to train neural net work or anfis system to classify my image for brain tumor

OK, here it is:
grayImage = imread('cameraman.tif');
[rows, columns, numberOfColorChannels] = size(grayImage);
row1 = round(rows / 3)
row2 = round(rows * 2 / 3)
col1 = round(columns / 3)
col2 = round(columns * 2 / 3)
i11 = grayImage(1:row1, 1:col1);
subplot(3, 3, 1);
imshow(i11);
i12 = grayImage(1:row1, col1+1:col2);
subplot(3, 3, 2);
imshow(i12);
i13 = grayImage(1:row1, col2:end);
subplot(3, 3, 3);
imshow(i13);
i21 = grayImage(row1+1:row2, 1:col1);
subplot(3, 3, 4);
imshow(i21);
i22 = grayImage(row1+1:row2, col1+1:col2);
subplot(3, 3, 5);
imshow(i22);
i23 = grayImage(row1+1:row2, col2:end);
subplot(3, 3, 6);
imshow(i23);
i31 = grayImage(row2:end, 1:col1);
subplot(3, 3, 7);
imshow(i31);
i32 = grayImage(row2:end, col1+1:col2);
subplot(3, 3, 8);
imshow(i32);
i33 = grayImage(row2:end, col2:end);
subplot(3, 3, 9);
imshow(i33);

That's basically it, just use 9 equations instead of 4, and 1/3 and 2/3 instead of 1/2.
Or see the FAQ for a more general situation: https://matlab.wikia.com/wiki/FAQ#How_do_I_split_an_image_into_non-overlapping_blocks.3F
