Hi,

I encountered some difficulties while trying to plot a function depending on a discrete parameter that I included in a for loop.

This is the code :

f(,,,,):=...; (rather complicated function 11 parameters)

with(plots):

tracer:=proc()
local p,k,L,ind:
L:=NULL:
ind:=...; (it is a 3x8 matrix)
for k from 1 to 8 do
for p from 1 to 8 do
L:=L,plot3d(f(x,y,ind[2,k],ind[3,k],ind[2,p],ind[2,p]),x=0..1,y=0..1,numpoints=1000):
end do:
end do:
display(L);
