# [✓] Interpolate values from "InterpolatingFunction" solution?

GROUPS:
 Hello everyone, I solved a two PDE simultaneously with "method of lines" using NDSolve command. Here is the code part of it: lines = NDSolve[{eqns, eqns2, initc1, initc2, initc3}, V[t], {t, 0, 5}, MaxSteps -> \[Infinity]] V[t_] = Table[v[i][t], {i, 0, n}]; I have obtained "InterpolatingFunction" solution: I want to obtain specific value of v[i][t], for example v[5][2] and also I want to obtain max. value of v[i][t] so max.v[3][t],max.v[2][t] etc. then plot a graphic with max. values respect the "i".How do I do this. Thank you
