## confusion...

i get the whole programme methodology but in my progrmme

res := dsolve({ics, ODE1}, numeric, abserr = .1, maxmesh = 8192)              what is maxmesh??

## i tried it...

i cant define u(x,y) like you have done because its an unknown function.

i have the matrix B as follows

now i want to multiply it with u(x,y).

i have tried your mentioned procedure more than once the output is

u(x, y) B

it doesnt work.
