_D_e_s_c_r_i_p_t_i_o_n:

     Creates artificial test signal identical to the standard test
     signals proposed and used by D. Donoho and I. Johnstone in WaveLab
     (a MATLAB toolbox developed by Donoho et al. the statistics
     department at Stanford University).

_U_s_a_g_e:

     makesig(sigName, N)

_A_r_g_u_m_e_n_t_s:

 sigName: Name of desired signal. Valid values are:

            SIGNAL.ALL
            SIGNAL.HEAVI.SINE
            SIGNAL.BUMPS
            SIGNAL.BLOCKS
            SIGNAL.DOPPLER
            SIGNAL.RAMP
            SIGNAL.CUSP
            SIGNAL.SING
            SIGNAL.HI.SINE
            SIGNAL.LO.SINE
            SIGNAL.LIN.CHIRP
            SIGNAL.TWO.CHIRP
            SIGNAL.QUAD.CHIRP
            SIGNAL.MISH.MASH
            SIGNAL.WERNER.SORROWS (Heisenburg)
            SIGNAL.LEOPOLD (Kronecker)

       N: Length in samples of desired signal (512 by default)

_V_a_l_u_e:

     Returns a list with components: 

       x: vector (or matrix) of test signals

       N: length of signal returned

_N_o_t_e:

     Using the value 'SIGNAL.ALL.SIG' for sigName returns a matrix 
     containing the vectors of all the other signals.
