CurveLab is a collection of Matlab and C++ programs for the Fast Discrete Curvelet Transform in two and three dimensions. For the 2d curvelet transform, the software package includes two distinct implementations: the wrapping-based transform and the transform using unequally-spaced fast Fourier trans- form (USFFT). Both variants are based on the Curvelet transform as described in ‘New Tight Frames of Curvelets and Optimal Representations of Objects with Piecewise C2Sin- gularities’, Comm. Pure Appl. Math. 57 (2004) 219-266. The implementation is also discussed in detail in ‘Fast Discrete Curvelet Transforms’, Multiscale Model. Simul. 5 (2006), no. 3, 861-899. We advise users to become familiar with these references. The two implementations diff er by the choice of spatial grid used to translate curvelets at each scale and angle.(CurveLab is a collection of Matlab and C++ programs for the Fast Discrete Curvelet Transform in two and three dimensions.

一款RS缩短码的源代码，可修改其中主程序的数据变任意一种RS码的编码器，此程序经多次验证均正确，且采用标准代码格式描写，易读。(A shortened RS code source code, which can modify data in the main program code change any of the RS encoder, this procedure has been repeatedly verified are correct, and the use of standard code format description, easy to read.)

积分分离PID控制matlab M文件代码。 该控制里面将积分分离，在控制误差很小时才重新使用积分，这样可获得更好的控制效果。(Integral Separation PID control matlab M file code. The control inside the integral separation, re-use integral control error is very small when, so to get better control effect.)
