Why the inbuild function used for bicubic interpolation results in different PSNR in MATLAB and OpenCV?

if we perform bicubic interpolation using matlab function: [nrow, ncol] = 2*size(im_l); im_b = imresize(im_l, [nrow, ncol], 'bicubic'); it shows PSNR =29.30 in MATLAB R2013a resize(img, im_b,...
