说明：  一个MATLAB写的BP神经网络原代码(write a MATLAB BP neural network original code!)

来自ptbdb数据库的信号的读取，该数据库内ECg信号的格式与传统的MIT-HIT数据库不同，是12导的数据，通过程序读取后，数据保存为Matlab矩阵的形式。(read ECG signal from the ptbdb database. Data form of this database is different from the tranditional "212" formal ECG signal. It returns ECG data of 12-leads in a matrix)

自适应采样,可以根据灰度变化的不同来进行采样。matlab代码(adaptive sampling)

本程序是在遥感图象处理中第一步,服务于内定向,用来确定框标图象中框标的重心位置.(this procedure is in remote sensing image processing first step in the services within orientation, standard used to determine frame image frame target focus position.)

本程序是有限时域差分源程序，有详细注解，方便学习理解。(This program is a limited time domain difference source program, has detailed notes, easy to learn to understand. )

space vector modulation for three phase induction motor open loop operation

说明：  Matlab中的一个小程序，用来计算指数值。希望大家给点建议。谢谢！ (Matlab a small program used to calculate the index values. We hope to the proposal. Thank you!)

牛顿迭代法 数值分析 求解方程组的解 这是一个matlab程序代码(newton iteration method)

here high pass is created using ideal high pass filter mask and applying FFT to the image. This will be very useful while performing filter step by step
