求解一维热传导方程，格式包括FTCS、BTCS、CNCS三种差分格式(solve one dimension heat transfer equation. )

这个我写的一个计算LC滤波器的程序，可以显示出最后的频率截止情况，有最平法，椭圆法等计算方法(this, I wrote a calculation of the LC filter procedures can demonstrate that the frequency of the final deadline, the most-France, oval law calculation method)

本程序是用数学方程试计算出一个点在一条线上的垂线坐标，并判断出在线内外，是测量中用的程序！(The test procedure is used to calculate the mathematical equation of a line a point in the vertical coordinate, and determine the line outside, the procedure used to measure!)

完成了复数矩阵的计算,采用了并行算法原理，较快速的处理了稀疏矩阵方程结构。(Completed a complex matrix computation, parallel algorithm principle, more rapid processing of the sparse matrix equation structure.)

圆周卷积滤波器，可清晰见到实际滤波器的算法(Circular convolution filter, can clearly see that the actual filter algorithm)

该软件主要应用是采用高斯正反算进行换带计算的。(The software application is used mainly Gaussian with positive and negative exchange balance calculation.)

以前用VB6编写的一个计算器，支持常用的数学函数，支持弧度、角度转换，支持简单的函数作图。(A calculator writen by VB6, supports common mathematical functions, support radian, angle conversion, support simple function mapping.)

基于GWBASIC实现的无约束寻优算法，内附GWBASIC主程序和说明(Non-binding on GWBASIC achieve optimization algorithm, the main program and instructions included GWBASIC)

用于求解超定方程组最小二乘解，稳定性高，速度快(To get the least square solution of superlattice dislocation.)
