### Tiling effect in MATLAB

Tiling effect

 original Image
Let’s make some random rectangles from the image.

MATLAB CODE:

C=uint8(zeros(size(A)));
i=1; j=1;
col=0;
row=0;
m=1;n=1;
%change the rsz and csz value to obtain pieces in different sizes
rsz=15;
csz=36;

%change the tsz_row and tsz_col values to make some gaps between the pieces.

tsz_row=3;
tsz_col=5;

while ( i < size(A,1))
%check whether i is less than size of (A,1)

while(m+i+row < size(A,1)&& n+j+col < size(A,2))

%size of the tiles varies depending upon the random number
C(m+i:m+i+row,n+j:n+j+col,:)=A(i:i+row,j:j+col,:);

m=ceil(rand(1)*tsz_row);
n=ceil(rand(1)*tsz_col);
col=ceil(rand(1)*csz);
row=ceil(rand(1)*rsz);
j=j+col;

end
i=i+row;
j=1;
end
figure,imshow(C);

Thank You a lot for this great effort,

I tried to use this code "Tilling effect",
But this error came up in the line of "while" Command:
"usage might be invalid"
I don;t know what is the solution for that.

@M. Selim
Sorry for the inconvenience. Html code was broken. I have corrected the problem. Now, the code will work without any error.
