其實也不是那麼的絕對.........
ibank的確是都是用C++的, 不過主要是for trading and etc., C++夠low level, trading速度重要
不過不少big financial instituion會用MATLAB, build up library的cost可以省下來.
再說MATLAB也more user-friendly.
R is very similar to MATLAB and is also very common.
另, 去banking做risk management的話, SAS is another common one as there're huge dataset.
Python and Java is not uncommon on job ad also.......
but anyway, C++ takes the most time to learn, and is generally a good word on CV to show one is good in quant develpoment even the firm don't use C++
P.S.
金融工程, at master level, 其實就是appled maths and stat with application in finance.......
finance易追回, programming也主要是要多用多練,
數學這玩意卻不是一時三刻可以追回, 更不是正常人可以自修的.....
非數理工的人去讀MFE, 就如建樓時, 只建四樓五樓, 但是沒有了下面的基礎一樣....
