Description: matlab程序语言，图像增强算法的代码- Function [U, minv, SS] = Nonlinear_Diffusion (U_0, tau, eps, p, T, theta, sigma, fig_handle)
Performs nonlinear scalar valued and coupled vector/matrix valued diffusion
Inputs:
U_0 nxmx dxw input field:
D = 1, w = 1: scalar valued diffusion (eg grayscale image)
D> 1, w = 1: coupled vector valued diffusion (eg color image)
D> 1, w> 1: coupled isotropic matrix valued diffusion (eg nonlinear structure tensor)
Of tau 1 x 1 (optional) time the step size
Eps, 1 x 1 (optional) epsilon for the diffusivity function
P 1 x 1 (optional) p of the diffusivity function:
P = 0 corresponds to homogeneous diffusion gaussian the smoothing
0 <p <1 corresponds to the forward diffusion

Description: T_XTIDE Tidal prediction
YOUT=T_XTIDE(STATION) makes a tidal prediction
for the current day using the harmonics file XTIDE. Predictions
at other times can be generated using [...]=T_XTIDE(STATION,TIM)
where TIM is a vector of matlab-format decimal days ( DATENUM).
If TIM is a scalar then it is taken as the number of days present
over which to make predictions. If TIM>1000 then it is taken to be
the starting time in matlab-format.
at the matlab time JD (UTC, but see code for details) where
tau = lunar time
s = mean longitude of the moon
h = mean longitude of the sun
p = mean longitude of the lunar perigee
np = negative of the longitude of the mean ascending node
pp = mean longitude of the perihelion (solar perigee)
