Hi,
I was wondering if there was a way in selectively specifying some of
the arguments of a function (rest remaining default). For instance,
consider
Clear[f, x, y,z];
f[x_: 1, y_: 2,z_:3] := {x, y}
f[5]
{5,2,3}
Here the default values of y and z are automatically used. How can I
call f so that, for example, the default value of x and z are used
instead?
Thanks,
NP
