indices of the maximum values in vector v

[aybike nurocak]

[y,v] = max(a) returns the indices of the maximum values in vector v
on Matlab. How can I do this on Maple 13 ?

a=[1 2+i]

a =

1.0000 2.0000 + 1.0000i

>> [c,d]=max(real(a))

c =

2


d =

2
I need to do the same on Maple..

Thanks

You can use rtable_scanblock for this

V := <1,2,4,3>:
rtable_scanblock(V
, [rtable_dims(V)]
, (val,ind,res) -> `if`(val>res[2]
,[ind,val]
,res
)
, [ [1,1], V[1] ]
);
[[3], 4]

However, a simpler method is to use member

member(max(V),V,'pos');
true
pos;
3
