Le Descripteur SIFT (Scale Invariant Feature Transform) [1] consiste a extraire un histo- gramme d orientations de gradients autour d un point d inter^et de l image. Le principe du calcul du descripteur est illustre a la gure

计算分段三次多项式插值的系数,计算三次样条插值函数的系数组M(Calculating the coefficients of piecewise cubic polynomial interpolation, cubic spline interpolation function calculating the coefficients M)

说明：  在matlab上实现图像同二维直角坐标系转化为极坐标秒的算法.(In matlab to achieve images with two-dimensional Cartesian coordinate system into polar coordinates algorithm seconds.)

perturb and observe tracking algorithm

This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a three-dimensional Cartesian space lattice comprised of uniform cubic grid cells. Each unit cell within the Yee lattice contains electric fieldcomponents sampled along the edges of the cube and magnetic field

无速度传感器的矢量控制系统仿真模型，为了实现转速的闭环控制和磁场定向(No speed sensor vector control system simulation model, in order to achieve closed-loop speed control and field-oriented)

very cool program finite element method

there is a matlab cod that describe how we can compute poincare map in general for nonlinear differential equation,in dynamical system.

Most defaults are determined by the filesystem superblock.
