argmax: Returns the index of the largest element in xs.
argmin: Returns the index of the smallest element in xs.
bincount: Bins the entries in xs into k bins.
choose2ixs: Choose two distinct random numbers in [0, …, n-1]
cumsum: Cumulative sum of xs
is_index_col
logaddexp: Perform ln(exp(x) + exp(y)) in a more numerically stable way
mean: The mean of a vector of f64
mean_var: Compute the mean and variance faster than by calling mean and var separately
minmax: Returns a tuple (min_elem, max_elem).
parse_result: Attempt to turn a &str into a T
sign: Like signum, but return 0.0 if the number is zero
std: The standard deviation of a vector of f64
transpose
transpose_mapvec: Turn Vec<Map<K, V>> into Map<K, Vec<V>>
unused_components: 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
var: The variance of a vector of f64
