The content medium between “portfolio optimizer in Excel for three stocks†and “hardcore matrix math for an arbitrary range of shares†is to use a quadratic programming solver. Some context is necessary to see why This can be the circumstance.
In the above imaginary instance, the return benefit is filled with aspects through the if_yes and if_no arguments which can be based on whether or not the ingredient of exam is Genuine or Bogus. For example, suppose we have a vector of Test marks. ifelse() could be accustomed to classify them as find here pass or fail:
