Error in k means clustering code. 'Error using reshape Number of elements must not change. Use [] as one of the size inputs to automatically calculate the appropriate size for that dimension.' The code is here.

grayImage= imread('CYST RENAL-33.jpg');
g = rgb2gray(grayImage);
imshow(grayImage);
b=grayImage(:);
[m n]=kmeans(b,3);
m=reshape(m,size(grayImage,1),size(grayImage,2));
B=labeloverlay(grayImage,m);
figure;
imshow(B);

Pls help me to solve this error. Any help is appreciated

This line:

b=grayImage(:);

Should be replaced with:

b = g(:) ;
