说明：   用最速下降法求最优化解 输入：f为函数名 grad为梯度函数 x0为解的初值 TolX,TolFun分别为变量和函数的误差阈值 dist0为初始步长 MaxIter为最大迭代次数 输出: xo为取最小值的点 fo为最小的函数值 f0 = f(x(0))( Steepest Descent Method with Optimum Solution input: f as a function name grad is gradient function x0 for the solution of the initial TolX, TolFun variables and functions were error threshold dist0 as the initial step MaxIter maximum Diego passage number Output: xo to take the minimum point of fo is the smallest function value f0 = f (x (0)))

这个程序可以实现牛顿环(Newton s rings)的演示, 其中可调参数包括波长, 透镜曲率半径及最低点空气缝隙的厚度.参数的调节是通过欢快实现的,其中颜色 随波长近似的变化. 本程序可以增进读者对牛顿环的理解.(this procedure can be achieved Newton Central (Newton's rings) demonstration. with adjustable parameters including wavelength, lens curvature radius and minimum thickness of the air gap. Parameter adjustment is achieved through the jubilant, With these color changes in the wavelength approximation. The procedure can improve readers to understand the Newton ring.)

Determine the SNR for a quadrature delta-sigma modulator using simulations. The modulator is described by a noise transfer function (ntf) and the number of quantizer levels (nlev). The ntf/stf may be given in ABCD form. The band of interest is defined by the oversampling ratio (R) and the center frequency (f0).
