Sounds like a vanilla numerical math course?
I’ve also recently noticed that programs and students outside North America seem to take the content much more seriously.
That was in Germany in the early 2000s.
I do know that this course is still offered widely across the US, but maybe not within CS, and maybe not as a mandatory course.
But, bottom line: if you're interested, it's very likely you can take it - you may have to check your school of engineering or applied math department.
