用于ocr图片字母提取的matlab代码，完全自己研究的(Ocr picture letters for extraction matlab code, complete theirself studies)

说明：  灰度共生矩阵和灰度梯度共生矩阵提取纹理特征，用matlab实现的(Graylevel co-occurrence matrix and grayscale gradient co-occurrence matrix extraction means)

说明：  用于地震数据的拉冬变换,可以分离直达波，折射波河反射波(use to radon change)

粒子滤波目标跟踪程序，地面雷达跟踪一个下落物体的弹道系数、速度和位置。(Particle filter target tracking procedures, ground radar tracking ballistic coefficient, velocity and position of a falling object.)

直接法，间接法，AR普 功率谱估计,其他的自己看文档就能明白了(Direct method, indirect method, AR & P power spectrum estimation, the other will be able to understand a document that looks at)

在Kraken简正模模型中，用于更改*.FLD场文件的matlab程序(Kraken normal mode model for change* FLD field file matlab program)

本代码为matlab编写，编程实现信号经过QPSK调制后，再经过AWGN信道下，得到的误码率性能曲线，并且与理论上的误码率进行对比。(The matlab code is written in programming through the QPSK modulation signal, and then through the AWGN channel, the resulting bit error rate performance curve, and with the theoretical bit error rates were compared)

matlab帮助文档，详尽讲述了一些函数的用法，具有一定的参考价值 (matlab help document, described in detail a number of function usage, has a certain reference value)

不是直接调用函数，直接计算出IIR参数的IIR滤波器设计。一共12个滤波器，从IIR一阶和切比雪夫滤波器都有。(not directly call functions directly calculated parameters of IIR IIR filter design. A total of 12 filters, IIR from a band and the Chebyshev filter has.)
