simple basic buck circuit

说明：  探究粒子群算法对电机的估计，具有重要意义。(It is important to explore the estimation of the motor by particle swarm.)

jpeg2000的matlab实现，包括实现的ppt。对图像处理和JPEG2000加密的朋友很有帮助。(JPEG2000 of Matlab realized, including the realization of ppt. Right JPEG2000 image processing and encryption of helpful friends.)

smgp jar 可以根据需要调用相应的jar包完成程序的开发(smgp jar)

三维 电磁波 有限差分 本来用于计算三维GPR正演，还不是最终版，还在调试PML边界(3D FDTD)

目前比较流行的稀疏分解重构程序，可以用在人脸识别、字典构造等方面。(Currently popular sparse decomposition and reconstruction process, can be used in face recognition, dictionary structure and so on.)

使用迭代式阈值算法来提高图像对比度。可以指定某个色阶作为阈值，所有比阈值亮的像素转换为白色；而所有比阈值暗的像素转换为黑色。 (The use of iterative threshold algorithm to enhance image contrast. You can specify a color scale as the threshold, all pixels lighter than the threshold into white and all pixels darker than the threshold value is converted to black.)

matlab计算拟合三维数据，并成三维图(a program which draw a 3_D drawing)

本程序是实现电力系统的故障计算程序，故障后会对导纳矩阵进行修正，很好的进行了仿真(This program is a power system fault calculation program, fault admittance matrix will be revised, a good simulation)

深度学习领域，dbn网络的训练代码，已经证实能够正常使用，用于matlab仿真专用(the dbn net code in deep learning )
