Multiple student course enrolment report

I am trying to prepare a report that tells me how many students have done course ABC and course XYZ.

Our data output contains one record per student per course. So if a student has done more than 1 course, they will appear in the data for how many courses they have done.

The ideal outcome is to get a matrix styled report that looks like below:

Course Names          Course A   Course B   Course C   Course D
Course A                  -         5          0          20
Course B                  5         -          6           7
Course C                  0         6          -           1
Course D                  20        7          1           -

Can anyone suggest a solution to achieve this?
