5.14 Sort Functions

See the sorting functions section for examples of how the functions work.

vector sort_asc(vector v)
Sort the elements of v in ascending order

row_vector sort_asc(row_vector v)
Sort the elements of v in ascending order

vector sort_desc(vector v)
Sort the elements of v in descending order

row_vector sort_desc(row_vector v)
Sort the elements of v in descending order

int[] sort_indices_asc(vector v)
Return an array of indices between 1 and the size of v, sorted to index v in ascending order.

int[] sort_indices_asc(row_vector v)
Return an array of indices between 1 and the size of v, sorted to index v in ascending order.

int[] sort_indices_desc(vector v)
Return an array of indices between 1 and the size of v, sorted to index v in descending order.

int[] sort_indices_desc(row_vector v)
Return an array of indices between 1 and the size of v, sorted to index v in descending order.

int rank(vector v, int s)
Number of components of v less than v[s]

int rank(row_vector v, int s)
Number of components of v less than v[s]
