FFT

我收集的老外编的椭圆拟合算法，C++实现，输入一组XY数据就能求出椭圆参数(I collected foreigner series the oval fitting algorithm, C++, achieve)

提供函数能进行1维2维的FFT，输入输出的序列长度应为2的整数次方倍(Provides functions can be one-dimensional two-dimensional FFT, sequence length input and output should be an integer power of 2 times)

数值计算的算法，采用c++实现，移植容易，一定能够用。(Data processing)

开发环境没有可选项，fortran90,Fortran_90_and_Computational_Science-_codes(Computational Science codes by fortran90 )

椭圆曲线密码体制中的ECC校验验算法分析和程序实现可直接使用。 (The inspection algorithm analysis and procedures of the elliptic curve cryptosystem ECC can be used directly.)

计算热轧中的单机架的轧制压力，采用的是SIMS公式，(rolling force calculation)

基于TMS320LF2407的FFT算法的实现及应用(TMS320LF2407 of the FFT algorithm based on Implementation and Application of)

复数的四则运算完整版，包括加减乘除，阶乘，开方等。。。(The plural arithmetic full version,, including addition, subtraction, multiplication, and division factorial, prescribing, etc...)

c++编写的小波包算法，可以实现小波包分解与重构，速度较快(A wavelet packet implementation written in C++, does wavepacket decomposition and reconstruction quite efficiently)
