Hello,

I have a big problem with the plot command :

I have tried to do a densityplot with cylindrical coords, but it doesn't work, it seems that maple can't do it. Do you have any suggestion to do this ?

So I decided to switch to plot3d - contourplot even if i would rather like densityplot. The problem is that i can't show the whole plot : maple only shows me a quarter of what i want :

contourplot( f (r,alpha), r=0..5, alpha = 0..2*Pi, coords=cylindrical );

where is the rest of the function ?

gerald

thanks for your help !

Hello,

I'd like to create a multiple variables function with a procedure, the problem is that the number of vars depends on the parameter n :

f:=(x1, x2, ..., xn) -> ...

how to define this function ?

I ve tried to do this, but i doesn't work :

var:=seq(d[i],i=1..n)
f:=(var)-> ...

even with a array instead of the seq, it doesn't work ... i'm desperate

thanks !
