Floyd算法又称为插点法，是一种利用动态规划的思想寻找给定的加权图中多源点之间最短路径的算法，与Dijkstra算法类似。该算法名称以创始人之一、1978年图灵奖获得者、斯坦福大学计算机科学系教授罗伯特·弗洛伊德命名。
Floyd algorithm, also known as interpolation method, is an algorithm that uses the idea of dynamic programming to find the shortest path between multi-source points in a given weighted graph, which is similar to Dijkstra algorithm. The algorithm is named after Robert Freud, one of the founders and winner of the Turing prize in 1978 and professor of computer science at Stanford University. (2020-07-18, matlab, 332KB, 下载0次)

TIMEOUT = LOGINTIMEOUT(FIRSTARG,SECONDARG) returns the current
value of time allowed for a connection to a database to be
successful. FIRSTARG, an optional argument, is a string that
specifies the JDBC driver to be used establishing the database
connection. SECONDARG, an optional argument, is an integer that
specifies the length of time the driver will attempt to make a
connection to a database. If FIRSTARG is not specified then the
default JDBC/ODBC bridge is used to establish the connection to
