What is this link exsactly?

[Walter Roberson]

when you read the documentation of how camera calibration works it says it is based upon a particular paper as implemented by a third party toolbox that it gives link to. That link in turn tells you that the code is included in the open source OpenCv toolbox. Which is what MATLAB calls .

You asked for a link to the open source implementation that MATLAB uses and that is the link: it calls a routine from OpenCv.
