algorithms(CPP)

采用数值分析课程中的插值逼近以及曲面拟合方法来估算复杂的函数表达式。(Interpolation approximations and surface fitting methods are used in the numerical analysis course to estimate complex function expressions.)

圆周卷积滤波器，可清晰见到实际滤波器的算法(Circular convolution filter, can clearly see that the actual filter algorithm)

实现1到1000位的大数运算（包括加减乘除和浮点数运算），运行环境是vs2005(1-1000, large number operations (addition, subtraction and floating-point), the operating environment is vs2005)

FFT/IFFT 变换程序----------------(FFT/IFFT transformation process----------------)

说明：  最小二乘法拟合曲线的一个小程序，采用C++程序，(Least-squares fitting curve C++ program)

c语言程序编写在经验模态分解，包含三次样条(c language programming in the empirical mode decomposition, contains the cubic spline)

用流体计算李指数的。是用excel中的vba做的小程序。(calculated the lyapunov exponent)

提供基二FFT(频域)的C语言算法,希望对大家有用()

本程序包括：DFT（离散傅里叶变换），FFT（快速傅里叶变换），IFFT（快速傅里叶逆变换），conv（卷积：圆周卷积、线性卷积），主要应用于信号处理，既可以对实序列做上述操作，也可以对复序列。(This process includes: DFT (Discrete Fourier Transform), FFT (fast Fourier transform), IFFT (inverse fast Fourier transform), conv (convolution: circular convolution, linear convolution), mainly used signal processing, either on the actual sequence to do the operation, can also be complex sequence.)

多物理场耦合软件采用有限元方法模拟rtfindgen(Coupled multi-physics simulation software using the finite element method rtfindgen)
