说明：  该程序代码用于求解超越方程，绘制频散曲线，自行可以更改基本参数或方程形式加以利用(Solve the transcendental equation, draw the dispersion curve)

Control optimisation. It is example of use BFGS algorithm to control satellite form Earth atmosphere to the Mars. Controled is engine power (bang-bang type) and angle of nozze.

七节点潮流计算，电气工程专业电力系统专业重要计算算法。(Seven node flow calculation, electrical engineering power system professional calculation algorithm.)

TRAINPSO is a network training function that updates weight and bias values according to particle swarm optimization.

说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

求数字1到10000的原根，返回原根值，若无原根显示说明(Find the numbers 1 through 10,000 of the original root, return the root value, in the absence of the original description of the root shows)
