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
