 lyngby_lz_lambda	- The Lange-Zeger hemodynamic response function

       function Lambda = lyngby_lz_lambda(Theta1, Theta2, Time, ForceOne);

       Input:  Theta1    A row vector with theta1 parameters
               Theta2	  A row vector with theta2 parameters
               Time      A column vector with sampletime
               forceOne  If 'ForceOne' is nonzero then force
                         distribution to one. 
	
       Output: Lambda	  Evalution of the function

       This function is the same as the gamma distribution function. 
       The theta1 is the shape parameter; theta2 is the scale
       parameter. The theta1/theta2 ratio is the center of mass for
       the kernel. Theta1 should be larger than 1 to yield an
       increasing curve in the beginning.
