Impulse response of a continuous-time Gaussian filter

Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.

这是用matlab编写的求解二维光子晶体的程序。(It is written in matlab program for solving two-dimensional photonic crystals.)

使用Matlab去LOCATE语音信号，尤其是UNVOICED的语音信号(how to locate the beginning and end of the speech, especially when the signal start from the unvoiced character)

ocr mean data is to calculate ocr data.

计算声压级平均值的四种方法：算术平均法，声压均方根平均法，能量平均法等(Four methods to calculate the average of sound pressure level are arithmetic average method, pressure square root mean method, energy averaging method and so on)

Rayleigh Fading Ampalitude without Phase Fading, The key point for ONES is that, in some modulation schemes like DPSK the phase error can not destroy the results.

This text provides an introduction to the numerical methods that are typically encountered (and used) in science and engineering undergraduate courses. The material is developed in tandem with MATLAB which allows rapid prototyping and testing of the methods. The package MATLAB (matrix laboratory) pro- vides an environment in which students can learn to programme and explore the structure of the numerical methods. The methods included here are of a basic nature and only rely on material which should have been explored prior to the fi rst year undergraduate stage.
