Hi folks,
probably a stupid question but can't find the answer, so please help if you
can :)
I would like to evaluate a if.. else.. statement on a whole array. Actually
it's a bit more complicated, as I have a function that
previously was
function u2(x)
return 0.5*(u2_0(x)+u2_0(Lbox-x))-u2_0(Lbox/2)
end;
for some other defined function u2(x) and constant L_box. The thing is that
I could directly evaluate that on a scalar x and on an array.
Now I have to change it and check if x is smaller than Lbox/2, returning
the same as above if it is, or 0 otherwise.
I tried something of the form
function u2(x)
return x.>Lbox/2 ? 0 : 0.5*(u2_0(x)+u2_0(Lbox-x))-u2_0(Lbox/2)
end;
but that complains when x is an array. What would be the easiest way to
achieve this? It should work for both scalars and arrays...
Best regards and thanks,
Ferran.
