Given a matrix, find the minimal path from the top left to the bottom right by only moving to the right and down so that the summation is minimum.
Use linear index to show the path.
For example,
x=[ 2 2 2 2 2
10 10 10 1 2
20 20 20 1 2
30 30 30 30 2]The minimal path is -- [1 5 9 13 14 15 19 20]

Asif -- In the last problem of the test suite, there are two different paths through the matrix that lead to the same minimal summation.
oh..didn't see that
William,
I've commented out the last test suite.
can u kindly point out the other path u're getting?
The alternate path is:
[1 11 21 22 32 42 43 44 45 55 56 66 76 77 78 79 89 90 100]
Here's another alternate path for the last test suite (magic(10)).
[1 2 3 13 14 24 34 35 45 55 56 57 58 68 69 70 80 90 100]
