identify vector row

[Katjes]

having a vector(10) called (aic) including all AIC values of various equations (1-10), using
vector v1 = @cmin(aic)
identifies the minimum value of all equations, but how can I address the row of the vector, hence the number of the best equations
(I now that there is a command something similar to @dtoo, but I cann't remember)
