快速排序法和堆排序法Fortran90程序，其中快速排序法使用到了递归过程，因此对于堆栈要求较高(both Quicksort and Heapsort program are used for sort array. Note that a recursion process is used in Quicksort program, Thus it need require a relative high stack size.)

运用线性矩阵不等式(LMI)求解鲁棒优化问题。该LMI不等式求解代码，更具有一般性，结合matlab中help命令,能够方便的对新的LMI问题求解(This programme code is useful for the common optimization problem, combined with the description of matlab help statement, a new LMI problem can be easy to solve. )
