how to reduce a one-dimension tensor (vector) ?

[buaasun]

I know there are functions for reduce a multi-dimension tensor: reduce_with_axis, reduce_except_dim... but I can't any for one-dimension tensor?

for example: I want to get the sum of a vector, I need function like below

Tensor<cpu,1,int> vec={1,2,3};
int s=reduce<red::sum>(vec);
// s should be 6

How do I achieve this in mshadow?
