说明：  MATLAB在信号处理中的典型应用-MATLAB在傅里叶变换中的应用。(MATLAB in signal processing in a typical application-MATLAB in the Fourier transform applications.)

Fourier Transform + Gaussian

that the performance is improved by increasing N, and probability of detection can be improved by increasing N value even if the SNR is much lower, as long as N is large enough without noise uncertainty.

一维插值，里面含有一个实例，并且有计算机结果图。(One-dimensional interpolation)

利用卡尔曼滤波对温度实现估计和预测，结合当前时刻温度计的测量值，对上一时刻的预测进行校正，得到校正后的最优估计(Estimation and prediction of temperature using Kalman filter)

Hadamard Transform for PAPR reduction in OFDM

简单的matlab算法，很经典，用于波束形成，主要是MIMO雷达 (Simple matlab algorithm, very classic, for beamforming, MIMO radar)

该函数用来计算任意函数的一阶偏导数(数值方法),毕业设计有用，具有丰富的参数选项。( This function is used to calculate the arbitrary function of the first order partial derivative (numerical methods), Graduation useful It has a wealth of parameter options.)
