I have a cost data (cost) in a matrix form

p         L1      L2      L3

1     25      30      36

2     32      44      65

3     40      66     85

4     12      88     40

5     10      42     36

Now I want to call this data with the help of piecewise

I want to write this equation with the help of piecewise function

dexpr float profit =sum(j in p)(cost[j][1]*L[j]+cost[j][2]*M[j]+cost[j][3]*H[j]);

p is from 1 to 5, L M H are dvar

Please help!
