World Coord to Camera Coord Conversion in Camera Calibration is Incorrect?

In camera calibration, to convert from world coord to camera coord, Matlab uses below:

• (x,y,z)_camCoord = [X,Y,Z]_wldCoord*R + t

where R and t are rotationMatrix and translationVector of the output of "extrinsics". https://www.mathworks.com/help/vision/ref/extrinsics.html https://www.mathworks.com/help/vision/ug/camera-calibration.html

However, in openCV document, R and [X,Y,Z] are reversed:

• (x,y,z)_camCoord = R*[X,Y,Z]_wldCoord + thttps://docs.opencv.org/2.4/modules/calib3d/doc/camera_calibration_and_3d_reconstruction.html

Which one is correct?
