Some informations about SonyEricsson GM47 GSM module and suitable antennas.

This code computes the approximation of the convolution integral (*) between two functions, f(t) and g(t), sampled at the times t1,t2,...,tm (unit spacing), via the trapezoidal quadrature rule. To compute the integral with other than unit spacing, multiply the result by the spacing increment.

说明：  适合Matlab的初学者，主要讲了Matlab的一些基础知识，都很基本的。(Matlab for the beginner, the main speech of some basic knowledge of Matlab, very basic.)

SRIM is a software that does Monte Carlo simulation of ion implantations. It can estimate the distribution of ions and target damages after an implantation. SRIMRangeDist helps SRIM users to plot the ion distribution data a SRIM output with relative ease. In some occassions, SRIM users need to calculate the distribution statistics of a series of several ion implantations and do a trial-and-error work to get the optimal implantation parameters. Performing this kind of task manually in a data processing software can be a bit mundane. SRIMRangeDist allows users to plot multiple implantation profiles on the same graph, and it computes the total distribution and the 95 confidence interval of the distribution for a quick reviewing of many implantation scenarios.

Least-square curve fitting using polynomials is probably the most basic way to perform some parametric regression analysis. Foor basic tools for polynomial curve fitting are provided here. I also strongly recommend the exhaustive function POLYFITN
