Matlab中max函数在矩阵中求函数大小的实例如下: C = max(A)返回一个数组各不同维中的最大元素.如果A是一个向量,max(A)返回A中的最大元素.如果A是一个矩阵,max(A)将A的每一列作为一个向量,返回一行向量包含了每一列的最大元素.如果A是多为数组,max(A) treats the values along the first non-singleton dimension as vectors, returning the maximum value of each ve…

题目链接:Max Sum Plus Plus Plus 题意:在n个数中取m段数使得这m段数之和最大,段与段之间不能重叠 分析:见代码 //dp[i][j]表示前i个数取了j段的最大值 //状态转移:dp[i][j]=max(dp[k][j-1]+(sum[k+l[j]-sum[k]或者sum[i]-sum[i-l[j]) (0<=k<=i-l[j]) // 这种做法是O(n^2)的 //如果改成O(n)的呢? //需要加一个数组max_dp[i][j]表示前i个数取j段的dp最大值 //如果…
