2D partitioned cumulative sum Challenge

Given a matrix M with r rows and c columns, and two Boolean lists V of length r and H of length c, calculate the partitioned cumulative vertical and horizontal sums.

Rules


r and c are greater than or equal to one
H and V begin with a true value
The values in M are within your language's reasonable numeric domain.
Partitioning and summing begins in the top left corner.


Walk through

Given M:

┌──────────────┐
│ 1  2  3  4  5│
│ 6  7  8  9 10│
│11 12 13 14 15│
│16 17 18 19 20│
└──────────────┘


H: 1 0 1 0 0

V: 1 1 0 1

Split M into groups of columns, beginning a new group at every true value of H

┌─────┬────────┐
│ 1  2│ 3  4  5│
│ 6  7│ 8  9 10│
│11 12│13 14 15│
│16 17│18 19 20│
└─────┴────────┘


Split each group of columns into groups of rows, beginning a new group at every true value of V:

┌─────┬────────┐
│ 1  2│ 3  4  5│
├─────┼────────┤
│ 6  7│ 8  9 10│
│11 12│13 14 15│
├─────┼────────┤
│16 17│18 19 20│
└─────┴────────┘


Cumulatively sum each cell horizontally:

┌─────┬────────┐
│ 1  3│ 3  7 12│
├─────┼────────┤
│ 6 13│ 8 17 27│
│11 23│13 27 42│
├─────┼────────┤
│16 33│18 37 57│
└─────┴────────┘


Cumulatively sum each cell vertically:

┌─────┬────────┐
│ 1  3│ 3  7 12│
├─────┼────────┤
│ 6 13│ 8 17 27│
│17 36│21 44 69│
├─────┼────────┤
│16 33│18 37 57│
└─────┴────────┘


Result:

┌──────────────┐
│ 1  3  3  7 12│
│ 6 13  8 17 27│
│17 36 21 44 69│
│16 33 18 37 57│
└──────────────┘
