基于51单片机的信号产生于周期检测
通过51单片机的外部中断接收信号，用51单片机定时器0的工作模式2记时，准确的产生一定周期的方波。同时当外部中断检测到信号的下降沿则打开定时器1记时，当第二个信号来时，关闭定时器1，读取时间，显示数据。

平均因子分解法应用于正定矩阵
平均因子分解法，适用于正定矩阵First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies:
(1) U U = X
(2) U is upper triangular (that is, it has all zeros below the diagonal).
It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition. -Average factor decomposition method applied to positive definite matrix First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X = UU, where U is the square root matrix of X, and satisfies: (1) UU = X (2) U is upper triangular (that is, it has all zeros below the diagonal).

国产stc89c51对应矩阵键盘
资源描述在键盘中按键数量较多时，为了减少I/O口的占用，通常将按键排列成矩阵形式。在矩阵式键盘中，每条水平线和垂直线在交叉处不直接连通，而是通过一个按键加以连接。这样，一个端口（如P1口）就可以构成4*4=16个按键，比之直接将端口线用于键盘多出了一倍，而且线数越多，区别越明显，比如再多加一条线就可以构成20键的键盘，而直接用端口线则只能多出一键（9键）。
