this is a presentation that explains matlab in detail.useful for engineers

本程序，可以用了画混淆矩阵，请大家使用，谢谢(This procedure can be painted with a confusion matrix, please use, thanks)

simulation of single phase transformer

说明：  MATLAB下生成hilbert矩阵,直接输入一个大于零的参数,就可以生成该矩阵(MATLAB generated hilbert matrix, directly into a parameter greater than zero, we can generate the matrix)

带色彩恢复的多尺度视网膜增强算法（MSRCR）的原理、实现及应用。 (Multi-scale recovery of the retina with color enhancement algorithms (MSRCR) principle, implementation and applications.)

it describes about the histogram of an image

相机标定matlab源程序，包含测试图，可以为标定提供新的方法，很方便(Matlab source camera calibration, including test plans, we can provide a new calibration method, it is convenient)

加有高斯白噪声的两个正弦信号的的观测数据，分别用最小二乘法和总体最小二乘法估计其功率谱，并对两种方法的谱分析进行了比较(Plus a Gaussian white noise of the two sinusoidal signals of observational data, were used least squares and total least squares method to estimate the power spectrum, and spectral analysis of the two methods were compared)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )
