Vector from Matrix
...d like to get a vector of length 100 which collects the values from the following procedure: Take the sum of the minima of the two values from each row of columns 1 and 101, and divide it by the sum of column 101. Do the same for column 2 and 102, 3 and 103 and so on. Thanks a lot for your help.

I am pleased to welcome Alrik Thiem as a co-author of this package, his skills and knowledge have been paramount to developing the current code. This version has numerous changes in the code (probably too many to present in this email) and new additional functions. Most notably, the previous qmcc() function is now obsolete, gi...
