_D_e_s_c_r_i_p_t_i_o_n:

     This function returns a character string according to a particular
     format for naming 'ipndacw' matrices.

_U_s_a_g_e:

     rmname(J, filter.number, family)

_A_r_g_u_m_e_n_t_s:

       J: A negative integer representing the order of the 'ipndacw'
          matrix.

filter.number: The index number of the wavelet used to build the
          'ipndacw' matrix.

  family: The wavelet family used to build the 'ipndacw' matrix.

_D_e_t_a_i_l_s:

     Some of the matrices computed by 'ipndacw' take a long time to
     compute. Hence it is a good idea to store them and reuse them.
     This function generates a name according to a particular naming
     scheme that permits a search algorithm to easily find the
     matrices. 

     Each matrix has three defining characteristics: its _order_,
     _filter.number_ and _family_. Each of these three characteristics
     are concatenated together to form a name.

_V_a_l_u_e:

     A character string containing the name of a matrix according to a
     particular naming scheme.
