Returns the index of the largest element in xs.
Returns the index of the smallest element in xs.
Bins the entries in xs into k bins.
Choose two distinct random numbers in [0, …, n-1]
Cumulative sum of xs
Perform ln(exp(x) + exp(y)) in a more numerically stable way
The mean of a vector of f64
Compute the mean and variance faster than by calling mean and var separately
Returns a tuple (min_elem, max_elem).
Attempt to turn a &str into a T
Like signum, but return 0.0 if the number is zero
The standard deviation of a vector of f64
Turn Vec<Map<K, V>> into Map<K, Vec<V>>
Returns a vector, in descending order, of the indices of the unused
components in asgn_vec, which can take on values from 0…k-1
The variance of a vector of f64
