很好很实用的一个小程序！好好体会，有很大的收获(very good)

SURF_DETECTOR SURF (Speeded Up Robust Feature) is a robust image detector and descriptor, first presented by Herbert Bay et al. in 2006, that can be used in computer vision tasks like object recognition or 3D reconstruction. It is partly inspired by the SIFT descriptor.

可以看到 变步长未必会需要更长的时间 因为它是一种自适应的方式 如果某阶段情况理想的话 就会用最大步长来做 那就会很快 (can see variable step may not need a longer period of time because it is an adaptive way if a certain phase of the the ideal would be the greatest step will be to do it quickly)

由于一般的功率放大器不是线性的，且动态范围是有限的，所以当OFDM系统内这种变化范围大的信号通过非线性部件时，信号会产生非线性失真。( As the general power amplifier is not linear, and the dynamic range is limited, so that when a large range of variation within an OFDM system, the nonlinear signal components, the signal will produce nonlinear distortion.)

The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform. For Haar transform, the transformation matrix H contains the Haar basis functions hk(x). They are defined on a continuous, closed interval, x -[0, 1] for k = 0,1,2 ...,N -1 where N = 2n.( The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform.

企业的生产计划在利润最高，产量有限，考虑市场价格波动以及存储有限的生产基本情况下，进行加工 、购买的规划设计.在设计时要考虑产量、价格、储存容量以及混合硬度等因素对规划的影响。(Production plans to the highest profit, output is limited, consider the market price fluctuations, as well as limited storage, under the basic conditions of production, processing, purchase planning and design. Should be taken into consideration in the design of production, price, storage capacity, as well as factors such as mixed-hardness on the planning impact.)

带动量项的BP算法程序求解XOR问题，权值更新为批处理方式。(driven volume items BP algorithm XOR problem solving process, the right to update the value of the batch mode.)
