I have two matrices: matrix {a} <252x1> is a subset of matrix {b} <252x4000>. I need to determine the number of days before and after the values of matrix {a} occurred in matrix {b}. 

```
Example:

Matrix a  Matrix b
10       12 34 54 10
23       23 98 78 98
43       98 53 43 88
44       98 44 88 78

Output
1  1  1  10
23 1  1  1
1  1  43 1
1  44 1  1

Days
3 0
0 3
2 1
1 2

```
