Filename=strcat('fruits\',srcFiles(i).name);
I=imread(Filename);
imshow(I)
[x,y, z]=size(I)
I_1 = I(1:x/2,1:y/2,:);
I_2 = I(x/2+1):end,1:y/2,:);
I_3 = I(1:x/2,(y/2+1):end,:);
I_4 = I(x/2+1):end,(y/2+1):end,:);

Nice of you to share the full error message. I'd guess that the error is because x is an odd number and x/2 is a fraction, like 123.5.
For x/2 use xMid
xMid = floor(x/2);
Then for x/2+1 use xMid+1
