计算心理声学的一些参数，比如响度，sharpness，粗糙度等等。(Psychoacoustic calculation of some parameters, such as loudness, sharpness, roughness and so on.)

说明：  Jacobi的matlab程序是我同学编着玩的，我试了一下挺好，Jacobi迭代算法。(Jacobi s matlab program is edited by students, I play, I tried some very good, Jacobi iterative algorithm.)

MATLAB经典的算法程序，帮助学习MATLAB(classic MATLAB program)

Frame subtraction code written by me using matlab it takes a video s first frame and subtract each frame from it. it shows output video and input video side by side

使用线性模型对数据进行多项式拟合和正弦拟合(Polynomial and Sinusoidal Fitting of Data Using Linear Model)

说明：  通过编程，利用变步长的求积公式求解积分，具有较高的精确度(By programming, the integral can be solved by the quadrature formula with variable step size, which has high accuracy.)
