I have a list containing 500 rows, each of 37 elements; i.e., a 500 x 37 matrix.
My goal is to substract in each row each element from the first. My approach in mind is to call each list by a PureFunction and then to subtract the second element from the first, then the third from the first so in the end I would have a list with 500 sublists, each with 36 elements. I failed to figure out how to call single elements if, as in my case, the the list is called by a PureFunction. I also tried to work with slots, again failing to call the single elements of the already called list. I highly appreciat any help or comments!
