该程序是一个matlab与visual c++ 混合编程的例子，运用matlab的combuilder将matlab程序编译成dll，在C++里调用。(that the procedure was a Matlab c mixed with visual programming examples. using Matlab combuilder procedures will be compiled into Matlab dll, in the C calling.)

说明：  研究在matlab环境下，fft的实现以及用matlab产生各种滤波器包括用双线性变换法以及脉冲响应不变法实现。(Research in the matlab environment, fft implementation and produce a variety of filters using matlab including the use of bilinear transform and impulse response method to achieve the same.)

数字水印lsb算法。matlab实现。空域算法，替换各像素最低位，不可见性较强，适用于脆弱水印。(Lsb watermarking algorithm. matlab implementation. Airspace algorithm, replacing the lowest level of each pixel, invisible and strong, suitable for fragile watermarking.)

用稳定边界法整定公式来求P,PI,PID的个参数，其中G是已知被校正系统的开环传递函数,kp为比例系数， Ti为积分时间常数，Td为微分时间常数，输入参量Gc为校正器传递函数，p为系统开环极点的个数（不计重根个数，即多重根只计一个根）(With the Stable Boundary tuning formula seeking P, PI, PID' s parameters, of which G is known to be corrected and the system of open-loop transfer function, kp is proportional coefficient, Ti the integral time constant, Td for the differential time constant, input parameters Gc for the corrector transfer function, p is the number of poles of open-loop system (excluding the number of multiple roots, that is a multiple root only to the root))
