说明：  已知门诊时间C[i,3] 求解病人住院时间,此算法虽然有一定的局限行，但是可以根据入院期望值计算出来大体的的入院时间；使用是，要把里面的数据进行处理（只改变输入值和u 数据个数定义值（一般取较大值即可））
(Known patient time C [i, 3] to solve the patient length of stay, although this algorithm has some limitations line, but expectations can be calculated according to the general hospital of admission time use is necessary to process the data inside (only change the number of input values ​ ​ and u define the data value (whichever is greater value to the general)))
