MATLAB: Imrotate make image blur. Any solution

Question

I = imread('cameraman.tif');
L = imrotate(I,50);
M= imrotate(L,-50);
imshow(M)
x_corr = normxcorr2(I,M);
[max_c, imax] = max(abs(x_corr(:)))

I tested with above code to see the effect of imrotate had on image. The result if the correlation was 0.94, less than what i expected and the image M was blur.

Any way to rotate the image without effecting its pixel value?

Thanks

Thanks for the replies.

Does it means there are no way to preserve the pixel value after rotation?
