_D_e_s_c_r_i_p_t_i_o_n:

     Modify coefficients by thresholding or shrinkage. 

     This function is generic. 

     Particular methods exist for the following objects: 

_w_d _o_b_j_e_c_t the 'threshold.wd' function is used;

_i_m_w_d _o_b_j_e_c_t the 'threshold.imwd' function is used;

_i_m_w_d_c _o_b_j_e_c_t the 'threshold.imwdc' function is used;

_i_r_r_e_g_w_d _o_b_j_e_c_t the 'threshold.irregwd' function is used;

_w_d_3_D _o_b_j_e_c_t the 'threshold.wd3D' function is used; 

_w_p _o_b_j_e_c_t the 'threshold.wp' function is used;

_w_s_t _o_b_j_e_c_t the 'threshold.wst' function is used.

_U_s_a_g_e:

     threshold(...)

_A_r_g_u_m_e_n_t_s:

     ...: See individual help pages for details.

_D_e_t_a_i_l_s:

     See individual method help pages for operation and examples.

_V_a_l_u_e:

     Usually a copy of the input object but containing thresholded or
     shrunk coefficients.
