discrete sine or cosine transform using matlab

说明：  随机风速模型。采用白噪声作为基础，基于matlab/simulink仿真出基准风速为9m/s的随机风速模型。(Random wind speed model.Based on white noise, a random wind speed model with a reference speed of 9m/s was simulated by matlab/simulink.)

短期负荷预测通常是指24小时的日负荷预测和168小时的周负荷预测，本文主要预测的是日平均负荷，对于短期负荷预测(short-term load forecasts usually refers to the 24-hour daily load forecasting and 168 hours a week load forecasting, In this paper, the forecast is the average load, short-term load forecasting)

原始时域信号FFT 之后，使用半功率带宽法辨识阻尼~~(After the original time domain signal FFT using the half-power bandwidth method to identify damping ~ ~~)

学习matlab的傅里叶变化小程序，没问题额(Fourier transform of small learning matlab program, the amount is no problem)

The MWM is a multiscale multiplicative data model which is able to capture not only correlation structure but also `spikiness .   Here, it is shown in comparison with a multiscale additive model which can match only the correlations

矢量算法，计算声源位置。速度比较快，精度很高。(Vector algorithm to calculate the location of a sound source. Relatively fast speed, high precision.)
