introduction_to_matlab

说明：  把真彩图转换为灰度图，然后根据灰度级数和共生矩阵位移向量求解灰度图矩阵的共生矩阵(The true color pictures converted to grayscale, and then gray series and the gray level co-occurrence matrix to solve the displacement vector of the co-occurrence matrix matrix)

主要是是显示技术中的数值计算的范例程序，有长直接地金属槽等计算(Display technology in the numerical calculation)

Digital filter 数字滤波器与均衡器(Digital filter digital filter and equalizer)

光伏电池simulink仿真，不错的simulink模型(Simulink simulation of photovoltaic cells)

分别用矩形窗、汉宁窗、海明窗、三角窗和Blackman窗设计一 的线性相位带通滤波器，观察它们的3dB和20dB带宽，并比较五种窗的特点。(Respectively rectangular window, Hanning, Hamming window, triangular window and Blackman window design a linear phase bandpass filter, observe their 3dB and 20dB bandwidth and compare the characteristics of the five windows.)

说明：  提取短时能量，短时过零率，清音/浊音自相关函数(Extraction of short-term energy, short-term zero crossing rate, voiceless/voiced autocorrelation function)

Gaussian differential.

说明：  matlab高效编程程序源代码第七章，可以运行。(efficient programming source code matlab Chapter VII, to run.)

用matlab语言编的基于粗糙集理论的属性约简程序(matlab roughset)
