电力负荷预测是电力系统规划的重要组成部分，也是电力系统经济运行的基础，其对电力系统规划和运行都极其重要。利用粒子群算法优化支持向量机更加高效准确预测电力负荷。(The power load forecasting is an important part of the power system planning, and it is also the basis of the economic operation of the power system. It is very important to the planning and operation of the power system. Particle swarm optimization is used to optimize SVM to predict power load more efficiently and accurately.)

NEWTON-RAPHSON求解一个连续方程，f（X）=0，前提给一个初始值( NEWTON-RAPHSON ALGORITHM 2.3 To find a solution to f(x) = 0 given an initial approximation p0: INPUT: initial approximation p0 tolerance TOL maximum number of iterations NO. OUTPUT: approximate solution p or a message of failure)

利用FFT变换，对sine2进行频谱分析，画出频谱图 利用iir源程序对输入波形sine2进行低通滤波，并将结果输出至result.dat。 (Using FFT transform, spectral analysis of sine2, draw the spectrum graph use the input waveform iir source sine2 to low-pass filtering, and the results output to result.dat.)

//////// OFDMA //////////// No. of Subcarriers NS = 512 Input Generation x = rand(1,NS)>0.5 fftlength = 512

this program support ofdm systems using 8PSK modulation. ofdm utilize fft/ifft module to transmit parallel data streams

利用滤波器处理音乐文件，但文件的格式要为.wav(Filter processing music files, but the file format should be .wav)
