My head is about to explode.
I have an M by N array of floats. Associated with the columns are
['a','b','b','c','d','e','e','e'] note: already sorted so duplicates
I want to replace the 2 'b' columns with the sum of the 2 columns.
Similarly, replace the 3 'e' columns with the sum of the 3 'e' columns.
The resulting array still has M rows but less than N columns. Anyone?
Could be any harder than Sudoku.
