- I have a dataset. Columns represents different variables.
- A variable may start with NaN or any double type number.
- If it starts with double number it continues with double type numbers.
- If it starts with NaN, we do not know when it ends.
- Return the row index where last NaN is observed in overall dataset. (Think column-wise)
Input
[ 1 NaN 5 NaN 2
2 NaN 4 4 8
6 NaN 8 2 4
0 0 0 0 0]
should return 3 because last NaN is observed in third row.
Test suite may be changed!

there seem to be some problems with the testsuite, in particular some of those matrices contain different number of elements per row (e.g. perhaps "5,7" should be "5.7"). I guess the same applies to your example dataset where the last row contains only four numbers instead of five?
I have fixed test suite.
The example from the problem description isn't a valid matrix; the last row has 4 entries rather than 5.
