brede_mat_kummer

 brede_mat_kummer     - Kummer's confluent hypergeometric function

       F11 = brede_mat_kummer(a,b, M)

       Input:  a    First scalar parameter
               b    Second scalar parameter
               M    'Mat' or matrix
              
       Output: F11  'Mat' structure

       Kummer's hypergeometric function 1F1(a,b,z), i.e, confluent
       hypergeometric function of the first kind.

       For certain parameter combinations the function does not
       return a precise result.

       Example:
         brede_mat_kummer(1, 0.5, 0)
