the function is a subfunction in function undistortPoints which is belongs to the camera calibrator block.
Function undistortPoints can run successly, but when I try to see the detail code as the screenshot shown，the subfunction undistortPointsImpl is noted as nonexist. where can I find this function's detail code?

The function is a hidden method in toolbox/vision/vision/cameraParameters.m
However reading the source will not do you much good. The implementation involves calling lscftsh which is a function in a .p file so you cannot read the code for it

Thank you. Could I know if there is any public reference material for constructing function lscftsh? I'm trying to use distortion model that is different from classical one, so I can't apply the function to get undistorted points directly

Sorry, I have no idea how lscftsh might be implemented.
