open fun <U> mapColsToList(f: (Matrix<T>) ->U):List<U>

Takes each col in a matrix, passes them through f, and puts the outputs into a List. In contrast to this#mapCols, the usage of a list as the output container allows for arbitrary output types, such as taking a double matrix and returning a list of strings.


f - A function that takes in a Nx1 col and returns a Mx1 col. Note that all output cols must be the same length.
